Aerobic Respiration Sample Test Questions - Part 1

The following questions, from the Virtual Cell Biology Classroom, are designed to help students better understand this topic. All questions are based on material that can be found on the Aerobic Respiration Lecture Main Page.

1. Phosphorylation of ADP would be considered...

a. catabolism

b. a dehydration reaction

c. an endergonic reaction

d. an exergonic reaction

2. Glycolysis is...

a. catabolism

b. part of Kreb's Cycle

c. part of cellular respiration

d. a & c

e. b & c

3. Where does electron transport of cellular respiration happen within an animal cell?

a. plasma membrane

b. cytoplasm

c. nucleus

d. mitochondria

e. chloroplast

4. Glycolysis is the breakdown of what?

a. ATP b. ADP c. protein d. sugar e. lipids

5. How many net (# made - #used) ATP are produced in the cellular respiration stages of glycolysis through synthesis of acetyl CoA?

a. 2 b. 4 c. 16 d. 34

6. Which parts of cellular respiration generate the carbon dioxide that we breathe out?

c. one molecule transfers a monomer to another

d. people eat each other

8. Oxygen is vital to the process of aerobic cellular respiration. It allows aerobic organisms to derive a great deal more energy from glucose than anaerobic organisms are able to. What is the vital role that oxygen plays in cellular respiration?

a. It is a reactant in glycolysis, necessary for the breakdown of glucose into pyruvic acid.

b. Oxygen is a waste product of Kerb's cycle.

c. Oxygen is required to build the acetyl-CoA molecule.

d. Oxygen is the final electron acceptor in the electron transport chain.

9. Which stages of aerobic cellular respiration each result in a net gain of 2 ATP?

a. Glycolysis and Krebs Cycle

b. Glycolysis, generation of acetyl CoA and Krebs Cycle

c. Electron transport

d.generation of acetyl-CoA and Krebs Cycle

10. Which of the following is the process of adding a phosphate to ADP?

a. hydrolysis

b. redox reaction

c. dephosphorylation

d. phosphorylation

e. none of the above
