Discuss the mechanisms by which body cells generate adenosine triphosphate (ATP)

Question

What will be an ideal response?

Answer 1

Cellular respiration includes all of the oxygen-dependent processes by which energy from the breakdown of glucose is captured within chemical bonds which unite adenosine diphosphate (ADP) and inorganic phosphate into the body's preferred metabolic fuel, adenosine triphosphate (ATP). One process, glycolysis, energizes each glucose molecule so that it can be split into two pyruvic acid molecules to yield ATP. The Krebs cycle, located within the mitochondria, produces all the carbon dioxide and water that results during cellular respiration, and it yields a small amount of ATP as well. The electron transport chain, also located within the mitochondria, is the primary producer of ATP. Hydrogen atoms removed during glycolysis and the Krebs cycle are delivered to the protein carriers of the electron transport chain, which form part of the mitochondrial cristae membranes. There the hydrogen atoms are split into their positive ions and negative electrons. The electrons then travel from carrier to carrier in a series of steps that enable phosphate to attach to ADP to form ATP.
