During respiration the C-H bonds are broken by oxidation-reduction reaction and so carbon dioxide and water are also produced. The cellular energy-yielding process is called cellular respiration.
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.
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power almost all cellular reactions throughout the body.
First, respiration may refer to external respiration or the process of breathing (inhalation and exhalation), also called ventilation. Secondly, respiration may refer to internal respiration, which is the diffusion of gases between body fluids (blood and interstitial fluid) and tissues.
Cellular respiration uses organic molecules from food (for example, the sugar glucose) and oxygen to produce energy that is stored in the molecule adenosine triphosphate (ATP), as well as heat. Cellular respiration also produces carbon dioxide and water.
Respiration in biology is a fundamental process that allows living organisms to obtain the energy necessary for all life functions. It involves a series of biochemical reactions that break down nutrient molecules, primarily glucose, to release stored chemical energy.
