Cellular respiration is the process by which cells convert sugar and oxygen into energy. This energy is used for everything our bodies do, from moving to thinking. It happens in two main stages: glycolysis and the citric acid cycle. During glycolysis, glucose (a type of sugar) is broken down in the cytoplasm of the cell, producing a small amount of energy. Then, in the citric acid cycle, which takes place in the mitochondria, more energy is released as the glucose is further broken down. For example, when you eat an apple, your body uses the sugar in it to perform cellular respiration, producing energy that helps you run, jump, and play. This process also produces carbon dioxide and water as waste products, which we breathe out. Without cellular respiration, our cells wouldn’t have the energy they need to function.
