| The following are some statements regarding glycolysis: |
| A. Glycolysis is not regulated by pyruvate kinase. |
| B. Lactate can be an end product of glycolysis. |
| C. Glycolysis cannot function anaerobically. |
| D. In erythrocytes, the second site in glycolysis for ATP generation can be bypassed. |
| Choose the option with incorrect statement |
A) A and B
B) B and D
C) C and D
D) A and C
Correct Answer: D
Solution :
Pyruvate kinase is the enzyme involved the last step of glycolysis. It catalysis the transfer of a phosphate group from phosphoenolpyruvate (PEP) to adenosine diphosphate (ADP), yielding one molecule of pyruvate and one molecule of ATP. Transformation of glucose into lactate occurs when limited amounts of oxygen\[\left( {{O}_{2}} \right)\] are available.
