Definition and synonyms of key from the online English dictionary from Macmillan Publishers Limited.
Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.his potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
ATP is the molecule that cells use to get their energy. ATP is  produced either by photosynthesis or by cell respiration. Edit. Share to: 1  The Five Major Parts of the Brain At its most basic, the brain controls the body.uring cellular respiration energy is stored in ATP molecules. When ATP is converted in to ADP, this energy is released for cells to use. The conversion of ADP in to ATP requi â¦ res molecules of hexose sugar to break down.
