Glycogenolysis & Gluconeogenesis

Biology Asked by A learner on December 2, 2020

Is glycogenolysis and Gluconeogenesis is the same in the terms of product formed?

This doubt arrived when I was attempting true & false and the question was

Glucocorticoids stimulate glycogenolysis, lipolysis and proteolysis

The answer given was false because "Glucocorticoids stimulate gluconeogenesis, lipolysis and proteolysis"

One Answer

Hello and welcome A learner,

Glycogenolysis is the breakdown of the molecule glycogen into glucose.

Gluconeogenesis is the metabolic process by which organisms produce glucose and other sugars from non-carbohydrate precursors.

These processes arrive at the same product (Glucose).

Glucocorticoids stimulate the process of Gluconeogenesis but not the process of Glycogenolysis.

To elaborate...

Glucocorticoids are steroid hormones that stimulate production of glucose in the liver via Gluconeogenesis. But Glucocorticoids are not involved in the pathway of Glycogenolysis.

Therefore: Glucocorticoids do not stimulate glycogenolysis, lipolysis and proteolysis.

And the answer is false.
