Question

Which of the following increase in the liver during intense exercise?

A. Pentose Phosphate Pathway

B. Glycogenesis

C. ETC and oxidative phosphorylation

D. Glycolysis

E. TCA (Krebs)

F. gluconeogenesis

G. glycogenolysis

Answer 1

The answer is option F. gluconeogenesis.

Doing exercise makes our body to demand glucose for energy production. So when we start doing exercise body will produce glucose by glycogenolysis. This process involves production of glucose from the stored glycogen in the liver. But when we continue to exercise at an intense rate, liver glycogen will get depleted and liver starts to produce glucose from gluconeogenesis. This process involves production of glucose from non carbohydrates sources like amino acids, lactate and glycerol. Other mechanisms mentioned in the question do not involved in glucose production in liver during intensive exercises.
