Question
Chapter 16, Problem 34P
Interpretation Introduction
Interpretation:
The energetic barriers that prevent glycolysis to occur in reverse and the energy required to overcome this barrier needs to be determined.
Concept introduction:
Glycolysis is the process that occurs in the cytoplasm of the cell. It is the breakdown of one molecule of glucose into two molecules of pyruvic acid. During this process energy is released in the form of two moles of ATP. The purpose of glycolysis is to maintain the blood glucose level.
