Glycolysis MCQs with solutions
10 of the 12 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.
Where does glycolysis occur in a eukaryotic cell?
- A. Cytoplasm
- B. Mitochondrial matrix
- C. Inner mitochondrial membrane
- D. Chloroplast stroma
What is the net ATP gain from glycolysis for each molecule of glucose?
- A. 4 ATP
- B. 2 ATP
- C. 6 ATP
- D. 8 ATP
Glycolysis occurs in the
- A. cytoplasm
- B. mitochondrial matrix only
- C. chloroplast thylakoid
- D. nucleus
The end product of glycolysis from one molecule of glucose is
- A. two molecules of pyruvate
- B. one molecule of acetyl-CoA directly
- C. six molecules of carbon dioxide
- D. one molecule of lactate in every cell
Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R : Assertion A : ATP is used at two steps in glycolysis. Reason R : First ATP is used in converting glucose into glucose-6-phosphate and second ATP is used in conversion of fructose-6-phosphate into fructose-1, 6-diphosphate. In the light of the above statements, choose the correct answer from the options given below :
- A. Both A and R are true but R is NOT the correct explanation of A.
- B. A is true but R is false.
- C. A is false but R is true.
- D. Both A and R are true and R is the correct explanation of A.
What is the net gain of ATP when each molecule of glucose is converted to two molecules of pyruvic acid?
- A. Four
- B. Six
- C. Two
- D. Eight
A cell converts one glucose molecule to two pyruvate molecules but cannot reoxidise NADH after glycolysis. Which glycolytic requirement will eventually limit continued glucose breakdown?
- A. Formation of acetyl-CoA
- B. Supply of oxygen to hexokinase
- C. Regeneration of NAD+
- D. Operation of ATP synthase
If glycolysis produces four ATP but consumes two ATP per glucose, what is the net ATP gain?
- A. 2 ATP
- B. 4 ATP
- C. 6 ATP
- D. 0 ATP
During glycolysis, ATP is both consumed and produced. Why is the pathway still described as energy yielding overall?
- A. The pathway produces only NADH, not ATP
- B. No ATP is actually consumed
- C. All ATP comes from oxidative phosphorylation
- D. More ATP is produced in later steps than is invested initially
Which molecule accepts electrons during glycolysis and becomes reduced?
- A. NAD+
- B. FADH2
- C. Oxygen directly
- D. Carbon dioxide
Common mistakes in Glycolysis
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Doubling some glycolytic products but not all of them.
- Assumes all ATP-producing pathways directly require molecular oxygen.
