Glycolysis/Respiration Practice Problems

Question #1

Why is it important that the components of the oxidative phosphorylation pathway in mitochondria and the photo-phosphorylation pathway in chloroplasts are imbedded in membranes? (The inner mitochondrial membrane and the thylakoid membrane, respectively.)
