WebWhat is respiration? The release of a relatively large amount of energy in cells by the breakdown of food substances in the presence of oxygen. What is aerobic respiration?
WebWhen the water is added, the enzymes digest the starch to form sugars such as glucose. The yeast becomes active in the moist dough and uses sugars for respiration; aerobic at first followed by anaerobic as the oxygen supply runs out. The gluten makes the dough sticky, trapping any carbon dioxide produced by the yeast, causing the dough to rise. WebRespiration The need to release energy is an essential life process, so respiration continuously takes place in all organisms. The exothermic reaction gives out energy. Aerobic respiration Aerobic respiration occurs when Oxygen and glucose molecules react and release energy. The energy is stored in a molecule called ATP.
