Use your knowledge of amino acids for energy metabolism to select the term that best completes each description. Glucose cannot be made when amino acids are converted to_________ . In the TCA cycle, some amino acids enter directly and, therefore, can continue in the cycle to generate energy and_______ . When is available, the body can use and glycerol to make some non-essential amino acids.

Answers

Answer:

Acetyl CoA; glucose

Explanation:

Acetyl-CoA is a molecule known to be part of different reactions during carbohydrate, protein, and lipid metabolism. Pyruvate (also known as pyruvic acid) is a molecule whose decarboxylation produces acetyl-CoA. Glucose cannot be synthesized when amino acids are converted to Acetyl CoA because this molecule (Acetyl CoA) cannot be converted back to pyruvate. The citric acid cycle (CAC), also known as the tricarboxylic acid (TCA) cycle, is a group of biochemical reactions that release energy by oxidation of acetyl-CoA obtained from sources such as proteins, carbohydrates and fats. During amino acid metabolism, glucogenic amino acids and TCA intermediates can be converted into glucose through gluconeogenesis.

Answer:

The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food.

5 The theory of plate tectonics was, at first, rejected by most scientists. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. What is responsible for the change in how scientists think about plate tectonics? A New evidence was discovered that made scientists revise their ideas. B. Tectonic plates have begun to move faster and faster over time. C There are more people studying science now than in the past. D Scientists can now travel underneath the plates and observe their motion.​

Answers

Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).

What is Tectonic Plates?

Tectonic plates are also known as lithospheric plates. It is a massive, irregularly shaped slab of solid rock that is composed of both continental and oceanic lithosphere. The size of the plates varies greatly from a few hundred to thousands of kilometres.

The plates are the largest in the Pacific and Antarctic Oceans. Its thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere.

Earth's rigid surface known as the lithosphere acts as a skin that rests and slides over a semi-molten layer of rock called the asthenosphere. It can break into many different plates because of differences in the density of rock and differences in subsurface heating between one region and the next.

Thus, Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).

Explanation:

The DNA sequence TTT codes for the amino acid lysine. The DNA sequence TTC

also codes for lysine. What can you conclude from this information?

Answers

Answer:

The genetic code is degenerate and therefore mutations may go unnoticed.

Explanation:

Each triplet of nucleotide bases, which is known as a codon, encodes for a specific amino acid during translation. However, a single amino acid may be coded by different codons. It is for that reason that the genetic code is considered to be degenerate. In this case, Lysine amino acid can be encoded by both TTT (UUU in the mRNA) and TTC (UUC) codons, thereby a mutation T>C at the third nucleotide codon position does not affect the resulting protein (i.e., it is a silent mutation).

D: There would be no change to the phenotypes of the possible offspring, because the extra X chromosome would not be active.

Answers

Answer: C the male offspring would all be red-green color-blind, because of interference from alleles on the Y chromosomes

Explanation: College board got it correct

The male offspring would all be red-green colour-blind, because of interference from alleles on the Y chromosome. Hence, option B is correct.

What is colour blindness?

a diminished capacity to tell some colors apart. Frequently, the condition is hereditary. Medications and specific eye conditions are additional factors. Men are affected more than women.

Inherited color blindness is not treatable. Treating the underlying issue may be helpful if another condition is the cause of color blindness.

The X chromosome is where the genes that might cause red-green color blindness is handed down. Men are more likely than women to have red-green color blindness since it is X-chromosome-inherited. This is due to the fact that males inherit just one X chromosome from their mothers. Hence, option B is correct.

Which of the following processes includes all of the others?
Select one:
a. Passive transport
b. Osmosis
c. Facilitated diffusion
d. Diffusion

Answers

i think it is b as well!

Diffusion is  described as  the flow of individual molecules  through a semipermeable barrier from a region of higher concentration to a region of lower concentration. Therefore (D) is the correct option.



What are different types of diffusion ?

Diffusion is the flow of molecules down the concentration gradient. Various types of diffusions are :  

Simple Diffusion : Also known as passive transport is the method by which solutes are transferred through a semipermeable membrane or along a concentration gradient in a solution.
Facilitated Diffusion: The passive transport of molecules along the concentration gradient. It is a selective process, meaning that only specific molecules and ions can pass through the membrane.
Osmosis: A process where solvent molecules move from a less concentrated solution to a more concentrated one by tending to pass across a semipermeable membrane.

Therefore, option (D) includes all other processes.

The two sounds heard through the stethoscope during a heartbeat are known as lub and dub. If the doctor detects an unusual lub

sound, evaluate which description could explain the atypical sound.

Answers

Answer: the description that could explain the atypical sound is known as HEART MURMURS.

Explanation:

The doctor makes use of instruments like the stethoscope to listen to the sounds of the heart while examining a patient. The sound heard in a normal heart beat is described as a "lub" and a "dub" sound.

The "lub" sound, which is called the first heart sound, is associated with closure of the atrioventricular valves at the beginning of a systole and the "dub" sound,which is called the second heart sound, is associated with the closure of the semilunar ( aortic and pulmonary) valves at the end of systole.

HEART MURMURS usually occurs when there are abnormalities of the valves which may occur due to congenital heart defects. It is classified according to when it occurs and these includes:

--> systole murmurs: these occurs during the first heart sound and,

--> Diastole murmurs: these occurs during the second heart sound.

Therefore the description that could explain the atypical sound is known as HEART MURMURS

Answer:

b.) the mitral valve does not close after the systolic phase.
