Essential amino acids are amino acids that must be obtained through the diet. Non‑essential amino acids can be made biosynthetically. Classify the amino acids into either essential or non‑essential amino acids.
Answer:
Explanation:
There are at present 20 major amino acids produced in the body. These amino acids are important biological components in the body. They are the building blocks of proteins. Also essential in the synthesis of nucleotides including the DNA and RNA. There are different ways of classified these amino acids:
Essential and non essential. The essential amino acids cannot be synthesized from scratch in the body but has to be obtained from our diet, while non essential is produced by the body
Acidic, basic, neutral, polar, non polar etc.
The essential amino acids are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
While the non essential amino acids are: alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.

The general function of an enzyme in the body is to ________. The general function of an enzyme in the body is to ________. eliminate waste products from the blood act as a reactant in carbohydrate storage catalyze chemical reactions maintain homeostasis maintain a neutral pH
Answer:
catalyze chemical reactions
Explanation:
An enzyme is a proteinous substance that acts as biological catalysts and increases the rate of biochemical reactions in the body. Enzymes are specific in nature which is as a result of the structure/shape of its building block (amino acid).
Enzymes speedens the rate of a chemical reaction in living systems, which would normally not occur or occur at a much slower rate, without the presence of an enzyme. Enzymes acts on the reactants called Substrates by binding to them to form products but they are not used up in the reaction. Hence, enzymes are not reactants.
How does a catalyst influence a chemical reaction?
Answer: A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction. ... Remember that with a catalyst, the average kinetic energy of the molecules remains the same but the required energy decreases
Explanation:
Desribe the structure of amino acids including what makes amino acids different from each other
Answer:
1) Amino acid contains a central carbon atom attached to: an anime group, carboxyl group, hydrogen atom and a side chain
2) The side chain of each amino acid differentiates from one another
Please find the description below
Explanation:
Amino acids are monomeric chemical compounds that forms the make up of a protein. Amino acids , like every other chemical compound, have a structure. Amino acids have two functional groups i.e. amine group (-NH2) and carboxylic acid group (-COOH).
All amino acids, which are naturally 20 in number have basic parts in common namely: 1) a central carbon atom, also called the alpha carbon 2) a hydrogen atom 3) an amine group i.e. (-NH2) 4) a carboxyll group i.e. (-COOH)
These are the basic parts of all amino acids, however, the difference between the amino acids is found in the series of different atoms called Side chains or R group that attach to the alpha carbon. These R group makes each amino acid specific and different. For example, a side chain containing sulphur (CH3-S-(CH2)2) is the R group of methionine. Each amino acid has a different side chain attached to the basic structure listed above.
In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of misfolded proteins would be higher than normal. proteins would not be delivered to their appropriate cellular locations. ribosomes would not associate with the endoplasmic reticulum.
Answer:
the concentration of misfolded proteins would be higher than normal.
Explanation:
Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.

In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper? a review of modern human anatomical structure evidence of changing environmental conditions, with references the reasons competing hypotheses are wrong his opinion of what will happen to the survival of the human race
Answer:
Dr. Potts used environmental data to support environmental hypotheses capable of explaining human evolution
Explanation:
In this paper, the author stated that environmental factors have been fundamental for the emergence of adaptive traits during human evolution. In consequence, Dr. Potts explained how particular environmental factors and habitats might have shaped human evolution. For example, it has been hypothesized that dry savanna vegetation might have been a key environmental factor associated to the emergence of human traits including, among others, bipedality, making of tools from stones, the development of human brains, etc. In order to prove this hypothesis, the author recorded environmental data from different regions in Africa (Olorgesailie, Olduvai, Turkana, Zhoukoudian, etc), where it is believed that first hominids evolved about 6-8 million years ago.

Explain the process of breathing begin with inhalation and describe the route that the air takes to the lungs and what happens when the air reaches the lungs include in your description the terms mouth nose pharynx larynx trachea bronchi lungs alveoli carbon dioxide oxygen and capillaries..... PLEASE HELP PLEASE
Answer:
Please find the detailed explanation below
Explanation:
The breathing process is the process of breathing in, also called inhalation and breathing out, also called exhalation. Inhalation and exhalation are important processes for a smooth respiratory experience.
Air (containing oxygen) from our external environment enter our body system via our MOUTH or NOSE. The air then passes from the PHARYNX into the LARYNX or voice box, which connects into the TRACHEA or wind pipe, which conveys the air into the lungs via its branched tubes called BRONCHI. These pipes that air passes through in order to reach the lungs are generally called AIR WAYS.
Inhalation (breathing in) involves the taking in of air into the LUNGS (main organ of respiration). It occurs when the diaphragm (muscle separating the thorax from abdomen) contracts and moves downward towards the abdomen. This allows the lungs to expand, allowing air to enter into the lungs via the NOSE or MOUTH down the TRACHEA or windpipe.
As soon as air reaches the lungs, the air passes through the bronchi (tubular branches of the trachea) into the ALVEOLI or air sacs. The delivery of oxygen in the inhaled air is carried out in the CAPILLARIES (a blood vessel that carries blood) that surrounds the alveoli. This alveoli conveys oxygen from the lungs into the bloodstream and carbon dioxide out of the bloodstream into the lungs (a process called GAS EXCHANGE).
Breathing out or exhalation of the carbon dioxide in the lungs (waste product of respiration) occurs when the diaphragm relaxes and moves upward, causing the lungs to deflate as the carbon dioxide is released through the trachea into the mouth or nose where it leaves the body system.

When curare, a South American arrow poison, is placed on a nerve-muscle preparation, the muscle though a neurotransmitter is still being released from the nerve. Give a possible explanation for the action of curare (be sure to include specific details explaining does not contract when the nerve is stimulated, even how and why).
Answer:
In a muscle contraction,neurotransmitter acetycholine stimulate the post synaptic membrane of the neuron or the sarcolemma of the muscles cells at the motor end plate .This neurotransmission effect leads to the opening of ligand gated sodium channels.
Therefore action potential(Endplate potential) is transmitted across the synaptic juction to to the muscles to bring about contraction of muscles(effector) .Therefore Acetycholine is refereed to as excitatory hormone.
Curare works as competitive inhibitor of acetycholine at the motor end plate. It prevents the binding of Acetycholine with the endplate.Therefore, ligand gated Na+channels can not open, thus End potential can not be generated due to lack of depolarization, thus contraction of muscles is inhibited.
Thus,despite the fact that the neurotransmitter is produced, the curare has blocked the end plate.So, no muscles contraction will occur because ,no place for the the excitatory acetylcholine to bind with.Hence the the muscle cells are in the permanent state of relaxation (resting membrane potential).
Animals poisoned with this substance usually asphyxiate because of paralysis of the diaphragm, external and internal inter-coastal muscles and collapse of the lungs and therefore failure of the entire respiration muscles and system.Thus lack of oxygen from failed breathing.

Explain why mutations that replace S/T/N residues with A/L/W residues in the N-terminal region of transmembrane proteins that function as cell surface receptors could significantly disrupt that utility of these proteins as receptors.
Answer:
Serine (S), Threonine (T) and Asparagine (N) are primary binding sites of carbohydrates, and thereby they are required to form glycoproteins (i.e., glycosylation products)
Explanation:
A transmembrane protein (TP) is a particular type of protein that crosses the cell membrane in order to enable the movement of ions and molecules. Transmembrane proteins are divided into alpha-helical and beta-barrel proteins. The N-terminal region of transmembrane glycoproteins can be required for N-linked glycosylation, which is an enzymatic mechanism capable of attaching oligosaccharides to proteins in order to form glycoproteins (glycans). N-linked glycosylation is a posttranslational protein modification that has distinct functions depending on the cell type and the protein region involved in such modification. For example, in the surface of immune cells, the N-linked glycans are capable of dictating the migration pattern of these cells.
