The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP.Click to see full answer. Regarding this, what is the process that releases energy from food in the presence of oxygen?Cellular respiration ; the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen, begins with a chemical pathway called glycolysis.Similarly, what process occurs when an organism obtains and releases energy? Cellular respiration is the process by which cells obtain energy from glucose. During cellular respiration, cells break down glucose from food in the presence of oxygen, and releases energy. When cells need energy, they “withdraw” it by breaking down the glucose. Also Know, what happens when food is consumed and metabolized Why does this process release energy? The food we eat supplies the body with energy-rich molecules like glucose. On entering the cells of the body, these molecules are broken down in a series of steps to reform carbon dioxide and water, releasing energy to be used by the body.What type of energy is released during respiration?During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
