b. Adenosine Triphosphate

c. Phosphofructokinase

d. Phosphoglycerate kinase

e. Pyruvate kinase

2.

Which of the following chemical reactions does not occur during aerobic glycolysis?

Select one:

a. oxidation of NADH

b. phosphorylation of ADP

c. reduction of NAD+

d. enzymatic action of PFK

e. hydrolysis of ATP

3.

The prokaryotic enzyme DNA polymerase III performs a similar function to which eukaryotic enzyme?

Select one:

a. DNA gyrase

b. DNA polymerase II

c. DNA primase

d. DNA kinase

e. DNA polymerase epsilon and delta

4.

The oxygen that we use to metabolize food comes from the oxidation of what molecule?

Select one:

a. CO2

b. HCN

c. CH2O

d. water

e. glucose

Answer 1

Answer:

1). B. Adenosine Triphosphate

Explanation:

Fructose 6-phosphate +ATP à fructose 1,6-bisphosphate + ADP + iP

2). a. oxidation of NADH

Explanation: Oxidation of NADH takes place in electron transport chian.

3). b. DNA polymerase II

Explanation:

In prokaryotic cells, polymerase III is the major replicative polymerase, functioning in the synthesis both of the leading strand of DNA. The same role was played by DNA polymerase II in eukaryotes.

4). D). Water

Explanation: Water produces O2. The oxygen is used to oxidize glucose molecule.
