The conversion of PEP (phosphoenolpyruvate) to pyruvic acid results in the production of:
Show answer and explanation
Correct answer: Phosphofructokinase
Phosphofructokinase (PFK) is the primary regulatory enzyme because it catalyzes the irreversible rate-limiting step. It is allosterically inhibited by high levels of ATP and citrate.
