Glycolysis

12. Microbial Metabolism / Glycolysis / Problem 1

During glycolysis, ATP acts as an inhibitor for phosphofructokinase when the energy charge in the cell is high. What describes this process?

ANSWERS OPTIONS

A

ATP competes with ADP at phosphofructokinase's active site, preventing further glycolysis

B

ATP binds to an allosteric site on phosphofructokinase, causing a shape change that lowers the affinity for fructose-6-phosphate

C

Phosphofructokinase increases catalytic efficiency in response to elevated ATP concentrations, promoting more rapid glycolysis

D

ATP triggers proteolytic cleavage of phosphofructokinase, rendering it inactive
