Solution

The correct option is B pyruvate kinase
In the last step of glycolysis, the transfer of phosphate from PEP to ATP is catalyzed by pyruvate kinase.

Pyruvate dehydrogenase oxidizes pyruvate, and the product enters the Krebs cycle.

Enolase catalyzes the penultimate step of glycosis, in which PEP is formed.

Phophopyruvate dikinase is a key enzyme in gluconeogenesis.
