Cellular Respiration
Equation, Cycle, Process, Reactants, & Products
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. Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation. (For longer treatments of various aspects of cellular respiration, see tricarboxylic acid cycle and metabolism.)
