Chapter 10, Problem 11RQ

Summary Introduction

To review:

The way in which chemical coupling hypothesis or substrate level phosphorylation could not explain the reason for the mitochondrial membrane to be intact during ATP (adenosine triphosphate) synthesis, but the chemiosmotic theory could explain the same.

Introduction:

Phosphorylation refers to the addition of a phosphate group to any molecule. This process is mediated by enzymes called‘‘kinases.’’ Phosphorylation is of two types, namely, substrate level phosphorylation, and oxidative phosphorylation. Substrate level phosphorylation is a quicker and direct process, while oxidative phosphorylation takes place in stages.
