Chapter 21, Problem 21.80QP

Interpretation Introduction

Interpretation:

The physiological function of gluconeogenesis has to be determined.

Concept Introduction:

In mammals, the only source of energy for brain cells and red blood cells is glucose. Also, both brain cells and red blood cells are not able to store glucose, and thus they need a continuous supply as blood glucose. This supply can be fulfilled by the degradation of glycogen by either gluconeogenesis or by glycogenolysis.
