Homework Answers
ATP synthase - it is the enzyme which is involved in synthesizing ATP. It is possible by creating electrochemical gradient on driving protons from the intermembrane space.
Lipase is a lipid digesting enzyme and amylase is starch digesting enzyme. Acetyl CoA is a metabolic product. But it has no role in driving protons.

11. (13 pts) Electron transfer Electron transfer translocates protons from the mitochondrial matrix to the external medium, establishing a pH gradient across the inner membrane (outside more acidic than inside). The tendency of protons to diffuse back into the matrix is the driving force for ATP synthesis by ATP synthase. During oxidative phosphorylation by a suspension of mitochondria in a medium of pH 6.9, the pH of the matrix has been measured as 7.7....
