Detailed explanation-1: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Detailed explanation-2: -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.
Detailed explanation-3: -The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.
Detailed explanation-4: -Answer and Explanation: Cellular respiration is best described as E) changing of stored chemical energy in food molecules to a form usable by organisms.
Detailed explanation-5: -The word respiration is commonly used to describe the process of breathing in oxygen and breathing out carbon dioxide. However, the term more formally refers to the chemical process organisms use to release the energy from food, which typically involves the consumption of oxygen and release of carbon dioxide.
