Chapter 8.2, Problem 6LO
Summary Introduction
To describe: The process by which the proton gradient drives adenosine triphosphate (ATP) synthesis in chemiosmosis.
Concept introduction: The process in which ions are moved by diffusion across a semi-permeable membrane to synthesize ATP is known as chemiosmosis. This process takes place inside the mitochondria during the aerobic
