Question

The regulatory enzymes in gluconeogenesis are Group of answer choices

A) hexokinase, phosphofructokinase, and pyruvate kinase
B) glucose-6-kinase, aldolase, and enolase
C) pyruvate carboxylase, aldolase, and phosphofructokinase
D) glucose-6-phosphatase, fructose-1,6-bisphosphatase, pyruvate carboxylase, and phosphoenolpyruvate carboxykinase

Answer 1

The correct answer is D) glucose-6-phosphatase, fructose-1,6-bisphosphatase, pyruvate carboxylase, and phosphoenolpyruvate carboxykinase.

Step-by-step explanation:

Gluconeogenesis is a process where glucose is obtained from other molecules like pyruvate. The correct order of the enzymes would be, pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose-1,6-bisphosphatase, and glucose-6-phosphatase. Beginning with the pyruvate, which is the main product of glycolysis and obtaining glucose.
