The correct answer is b. use and make ATP.
Cellular Respiration and Photosynthesis both are very important physiological processes occur in green plants. Both these metabolic processes produce and use energy in the form of ATP. During cellular respiration and photosynthesis H+ build-ups the ATP Synthase transports the hydrogen ions down the concentration gradient to form ATP which are used during processes.This process is called Chemiosmosis.
