cellular respiration definition The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions (see metabolism) of an organism run. Note: The main carrier of energy in metabolism is the molecule ATP.
Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules. Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules.Animals obtain food molecules from plants and other organisms, and then undergo cellular respiration to obtain ATP molecules. Cellular respiration occurs at all times. â Photosynthesis involves conversion of one type of energy into another: light energy into chemical energy. â Cellular respiration involves using that chemical energy and breaking it down to release energy.
