Question

In which step glucagon completely blocks glycolysis

Answer 1

Lowered blood glucose triggers secretion ofglucagon and decreases insulin release (Fig. 22-22). ... But, unlike epinephrine, glucagon inhibits glucose breakdown by glycolysis in the liver and stimulates glucose synthesis by gluconeogenesis.

Answer 2

Explanation:

When glucose has been converted into G6P by hexokinase or glucokinase, it can either be converted to glucose-1-phosphate (G1P) for conversion to glycogen, or it is alternatively converted by glycolysis to pyruvate, which enters the mitochondrion where it is converted into acetyl-CoA and then into citrate.
