Question
Chapter 18, Problem 34RE
Interpretation Introduction
Interpretation:
The different reactions involved in substrate cycles are associated with different enzymes is to be explained.
Concept introduction:
Substrate cycling is a set of opposite reactions that are not in equilibrium. Such reactions are carried out by different enzymes in different reaction conditions and follow a unique mechanism pathway.
