Cellular Respiration: Or, How one good meal provides energy for the work of 75 trillion cells February 16-18, 2004 What's the difference between Cellular Respiration and Photosynthesis? Photosynthesis and respiration are reactions that complement each other in the environment. Photosynthesis and cellular respiration are used to produce usable energy for plants and other organisms. These processes occur on a molecular level inside the cells. Photosynthesis and cellular respiration are complementary biochemical reactions. Photosynthesis requires the products of respiration, while respiration requires the. Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. C 6 H 12 O 6 + 6O 2 + 6H 2 O → 12H 2 O + 6 CO 2 Chemiosmosis explained by an AP Bio student, for AP Bio students. Respiration. Photosynthesis. H+ ions pumped by ETC. Yes. Yes. ATP synthesis by chemiosmosis. Yes. Yes. Membrane-embedded ATPase complex. Yes. Yes Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of. Quiz: Cellular Respiration. 1.
