6.) Which compound has the highest potential energy and produces the most ATP when completely oxidized?...

6.) Which compound has the highest potential energy and produces the most ATP when completely oxidized?

a. acetyl-CoA

b. glucose

c. pyruvate

d. carbon

e. both pyruvate and carbon

7.) Which is TRUE about amphipathic molecules when placed in an aqueous solution (water)?

a. The interior portion is composed of hydrophilic hydrocarbon chains.

b. The outside portion is composed of hydrophilic head groups.

c. The interior portion is composed of hydrophobic hydrocarbon chains.

d. Both A and B

e. Both B and C

8.) On which of the following processes would a defective ribosome have the most detrimental effect?

a. translation

b. replication

c. transcription

d. replication and transcription

e. replication and translation

9.) The formation of bilayers by phospholipids is driven by:

a. hydrogen bonding

b. hydrophobic effect

c. non-polar covalent bonding

d. all of the above

e. A and B

10.) C6H12O6 + 6O2 + ADP + Pi---> 6CO2 + 6H2O + ATP When is the majority of the carbon dioxide in this reaction produced?

a. glycolysis

b. Calvin cycle

c. Citric Acid cycle

d. conversion of pyruvate into acetyl-CoA

e. electron transport chain

Expert Solution

Q6. The correct option is B. Glucose.

From complete oxidation of glucose, 32 ATP is formed.

From complete oxidation of acetyl coA, 10 ATP is formed.

From complete oxidation of pyruvate, 12.5 ATP is formed.

Q7. Option E . Both B and C are correct.

Amphipathic molecules are thos having both hydrophobic and hydrophilic parts. When placed in water, hydrophilic are outside due to Hydrogen bond formation. And hydrophobic are at the interior part where the hydrophobis part for hydrophobic interaction and away from water.

Q8. Option A is correct. Translation.

Translation is the synthesis of protein, where it is done in ribosome. So if ribosome is defective then translation will be harmed.

Q9. Option E is correct . Both A and B.

Explainatiom is similiar to Q7.

Q10. Option C is correct. Citric acid cycle.

No CO2 is produced from glycolysis.

In calvin cycle CO2 is being used up and not produced.

In citric acid cycle, 2 CO2 is produced

In conversion of pyruvate to acetyl coA, 1 CO2 is produced

In ETC CO2 is not produced.

2. The hydrolysis of ATP is the cell’s most commonly used exergonic reaction when performing energy coupling. Explain energy coupling, why it is necessary, and how the hydrolysis of ATP fits into the process. Use vocabulary words such as “endergonic,” “exergonic,” “spontaneous,” and “nonspontaneous.” (8 points) Prokaryotic organisms do not have membrane-bound organelles. However, they are able to make ATP and survive. Assuming that bacteria cannot use their membranes to make ATP, which process can they still use in order...

6. Glucose is completely oxidized to carbon dioxide with the concomitant production of several reduced electron carrier molecules. Oxidative phosphorylation ensures the regeneration of these electron carrier molecules. A. Cell Y is able to carry out glycolysis, citric acid cycle, and oxidative phosphorylation. However, a certain mutation in ATP synthase allows the passage of H+ ions but does not produce ATP. When grown in aerobic conditions, would you expect Cell Y to generate a little less OR a little more...
