The Process Of Cellular Respiration
Cellular respiration is the process that release energy by breaking down glucose and other food molecules in the presence of oxygen. There are three steps I the process of cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is the process breaking one molecule of glucose in half, producing two molecules of pyruvic acid. If oxygen is present respiration will continue in the mitochondria. If oxygen is present or there is not enough to continue fermentation will take place. Fermentation release energy from food molecules by producing ATP and other byproducts in the absence of oxygen. There are two types of fermentation: lactic acid fermentation, and alcoholic fermentation. Alcoholic fermentation forms
