Which of the following correctly describes the role of biomolecules in energy storage ?
Answers
Answer:
Biomolecules are crucial to the storage of energy energy in the body.
Biomolecules conserve energy using covalent chemical bonds.
Explanation
A covalent bond in chemistry refers to a chemical bond that is formed when two atoms share a pair each of electrons.
So some of these molecules which have high energy (such as glycogen and triglycerides) are able to keep or store such energy in the form of covalent chemical bonds. Examples of energy-rich biomolecules are:
glycogen and triglyceridesCells synthesize such molecules and store them for later release of the energy.

Answer: B. Carbohydrates are used for short-term energy storage, and lipids are used for long-term energy storage.
Explanation:
Humans and animals use carbohydrates for short-term energy storage and are stored as glycogen which can be broken down into glucose when energy is needed.
Lipids are used for long-term energy and are stored as fats in the body. These fats can be broken into fatty acids when the body needs energy.

P680 is said to be the strongest biological oxidizing agent. Given its function, why is this necessary
Answers
Answer:
The correct answer is - it obtains electrons from the oxygen atom in a water molecule, so it must have a stronger attraction for electrons than oxygen has
Explanation:
P680 known as which contains a reaction center in photosystem two, it is a very strong oxidizing agent that catalyzes the transfer of electrons from H2O to a bound quinone, with the production of O2.
To have a stronger attraction for electrons than oxygen has, P680 gets electrons from the O2 atom in a water molecule.

A certain regulatory gene is involved in controlling the expression of other genes. In studying this regulatory gene, a scientist discovers that it encodes for an enzyme that causes histone deacetylase (the removal of acetyl groups from histone tails). Based on this information, how would you predict that this enzyme regulates gene expression
Answers
Answer:
by an epigenetic mechanism
Explanation:
Epigenetics can be defined as the study of mitotically heritable gene expression changes that do not involve alterations in the DNA sequence. There are three different epigenetic modifications that work together either to activate or repress gene expression: DNA methylation, histone modifications (e.g., methylation, acetylation, phosphorylation, etc) and regulatory non-coding RNAs (e.g., long non-coding RNAs, microRNAs, piwi-RNAs, etc). Deacetylases are enzymes that play roles in epigenetic gene regulation by removing acetyl groups from lysine (K) residues located at the N-terminal end of histones H3 and H4. Histone deacetylation modifies the structure of the chromatin, thereby activating or suppressing gene expression in a context-dependent manner.
Specialized proteins called cell cycle regulators, such as p53 and p21, regulate the progression of the cell cycle from one phase to the next. This progression through the checkpoints is strictly regulated and usually works without error. When errors do occur, they can have catastrophic consequences, including cancer. How did this study lend new evidence to our understanding of how genes regulate the cell cycle, giving us a better chance of developing successful cancer treatments
Answers
Answer:
The change in the genes p53 and p21 results in deficits in checkpoints that result in cancer of various types. The G2-HM checkpoint deficits can be exploited in the development of targeted treatment.
A mutation in the above normal functioning of p53 can lead to the progression of damaged cells to mitosis which leads to cancer. So therapeutics which target any of these checkpoints can lead to developing a treatment for cancer.

9. Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal
levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules
Will this patient be able to exercise normally?
a
Yes, as long as her cells have enough oxygen, her body will be able to exercise,
b
No, her cells need glucose to react with oxygen to release enough energy to exercise.
С
No, her cells need amino acids to react with oxygen to release enough energy to exercise.
d
No, her cells need glucose to react with amino acids to release enough energy to exercise.
Answers
Answer:
b. No, her cells need glucose to react with oxygen to release enough energy to exercise.
Explanation:
Living organisms are able to perform any of their day-to-day activities due to the release of energy in their individual cells. The process by which this energy is obtained by their cell is called CELLULAR RESPIRATION. Cellular respiration is the process whereby glucose (from digested food) is broken down in the presence of oxygen to yield energy in form of ATP. The general equation is as follows:
C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 + 6H2O + ATP
According to this question, a doctor is said to test a patient for the content of molecules in her cells. Her cells were found to contain normal levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules. This patient will NOT BE ABLE to exercise normally because her cells need glucose in optimal amount to react with oxygen to release enough energy to exercise.

The yeast used to make beer can perform aerobic respiration or alcoholic fermentation. When O2 is available, yeast perform aerobic respiration, and when O2 is not available, yeast perform alcoholic fermentation. What is the advantage of aerobic respiration
Answers
Answer:
Aerobic respiration generates a high amount of energy compared to anaerobic respiration.
Explanation:
Yeast is a unicellular organism that belongs to the kingdom FUNGI. Yeast is a phenomenal organism being that it is capable of both aerobic respiration and anaerobic respiration depending on whether there is availability or not of oxygen.
Yeast undergoes a type of anaerobic respiration called FERMENTATION in the absence of oxygen but when oxygen is present, it undergoes aerobic respiration. Note that aerobic respiration, which includes glycolysis, Krebs cycle, and oxidative phosphorylation, produces the highest amount of energy in form of ATP. This amount ranges from 32-34 ATP molecules. This is the major reason why aerobic respiration is advantageous over the anaerobic respiration.
