Question
Chapter 20, Problem 39RE
Interpretation Introduction
Interpretation:
The reason for the requirement of an intact mitochondrial membrane for ATP production is to be explained.
Concept introduction:
Coupling in oxidative phosphorylation is based on the difference in the concentration of protons in the intermembrane and the matrix. The proton gradient or the pH gradient is the crux of the matter.
Effect of the generation of pH gradient is one of the major reasons behind the intact mitochondrial membrane. This pH gradient inhibits the flow of protons across the inner mitochondrial membrane.
