Explanation:
Detailed explanation-1: -The first step of glycolysis is catalyzed by phosphofructokinase (PFK) and converts fructose-6-phosphate to fructose-1, 6-bisphosphate.
Detailed explanation-2: -Abstract. Background: Yeast pyruvate kinase (PK) catalyzes the final step in glycolysis. The enzyme therefore represents an important control point and is allosterically activated by fructose-1, 6-bisphosphate (FBP).
Detailed explanation-3: -The enzymes involved in the generation of ATP are glyceraldehyde-3-phosphate dehydrogenase (G3PD) and phosphoglycerate kinase (PGK).
Detailed explanation-4: -Five enzymes of the glycolytic pathway serve as substrates for purified epidermal-growth-factor-receptor kinase.
