Compare the following terms: cellular respiration, oxidative phosphorylation and chemiosmosis
What will be an ideal response?
Cellular respiration refers to the collection of intracellular reactions in which nutrient molecules are broken down to form ATP. During the process, oxygen is utilized and carbon dioxide is produced. Oxidative phosphorylation is the process by which ATP is synthesized using the energy released by electrons as they are transferred to oxygen; it takes place at the mitochondrial inner membrane. Chemiosmosis encompasses the last steps of oxidative phosphorylation and involves the production of ATP via the activation of ATP synthase. This enzyme is activated as H+ moves into the mitochondrial matrix.
