Cellular respiration is the process by which the chemical energy of food molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
Cellular respiration 1. Cellular respiration. Typical eukaryotic cell. Cellular respiration is the set of the. metabolic reactions and processes that take. place in the cells of organisms to convert. biochemical energy from nutrients into. adenosine triphosphate (ATP), and then. release waste products.[1] The reactions. involved in respiration are catabolic.
