Unformatted text preview: gradient is also used to produce ATP in the chloroplast (diagram below). In this case, sunlight provides energy to pump hydrogen ions into the thylakoid . The energy of their movement back into the stroma by osmotic pressure is used to produce ATP. The enzyme that uses a hydrogen ion concentration gradient to phosphorylate ADP is ATP synthase . Photophosphorylation and oxidative phosphorylation (discussed above) both use an osmotic concentration gradient of hydrogen ions to produce ATP, therefore these two processes are often referred to as chemiosmosis....
