Question 3

If during a chemical reaction, a molecule loses hydrogens, it could be described as being oxidized.

Accepted Answer

Losing hydrogens is a characteristic of oxidation.

Question 4

Both glycolysis and the citric acid cycle can be regulated by feedback inhibition. Provide two examples of feedback inhibition. ​

Accepted Answer

The answer of Both glycolysis and the citric acid cycle...

Question 5

Two mobile electron carriers that are important for the electron transfer system are cytochrome c and coenzyme Q.

Accepted Answer

Cytochrome c and coenzyme Q (ubiquinone) are both mobile electron carriers in the electron transport chain, playing crucial roles in transferring electrons between complexes within the mitochondrial inner membrane.

Question 6

During glycolysis, ATP is produced by oxidative phosphorylation.

Accepted Answer

ATP is produced during glycolysis through substrate-level phosphorylation, not oxidative phosphorylation.

Question 11

Explain why FADH₂ generates less ATP than NADH.

Accepted Answer

The answer of Explain why FADH₂ generates less ATP than...

Question 12

The key enzyme that regulates glycolysis by responding to changing levels of ATP is hexokinase.

Accepted Answer

The key enzyme that regulates glycolysis by responding to changing levels of ATP is phosphofructokinase-1. Hexokinase is important in the first step of glycolysis, but it is not the enzyme that responds to ATP levels to regulate the overall process.

Question 13

Both plants and animals possess mitochondria, which are used for some cellular respiration pathways to make ATP. ​

Accepted Answer

Mitochondria are present in both plants and animals and are involved in cellular respiration to produce ATP.

Question 14

During the process of pyruvate oxidation, pyruvate is broken down and the remaining two carbons are attached to coenzyme A.

Accepted Answer

During pyruvate oxidation, pyruvate is broken down into a two-carbon molecule called acetyl-CoA, and coenzyme A binds to the acetyl group to form acetyl-CoA.

Question 15

Glycolysis yields a net of 2 pyruvate, 2 NADH, and 2 ATP.

Accepted Answer

Glycolysis does indeed yield a net of 2 pyruvate, 2 NADH, and 2 ATP.

Question 18

Products of fermentation include NADH and FADH₂.

Accepted Answer

Products of fermentation typically include ethanol or lactic acid, and carbon dioxide, but not NADH or FADH2, which are instead consumed during the process to regenerate NAD+.

Question 19

The process of glucose biosynthesis is called gluconeogenesis.

Accepted Answer

Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources such as amino acids or fatty acids.

Question 20

Glycolysis takes place in the mitochondria.

Accepted Answer

Glycolysis actually takes place in the cytoplasm of the cell, not in the mitochondria.
