What is the connection between breathing and the electron transport chain?
“Cellular respiration = aerobic harvesting of energy from food molecules by cells. Respiration often used as synonym for “breathing”, which involves exchanges of gas. During breathing, O2 dissolves in lungs, is carried in bloodstream to all other body cells. Mitochondria in these cells use O2 in cellular respiration. During the breakdown of food molecules by cellular respiration CO2 is produced as a waste product, and diffuses out of cells into bloodstream where it is carried to the lungs and expelled.” “ETC is final stage of cellular respiration” Source and further information: http://www.langara.bc.ca/…/biol1116chap6.html Further information: http://www.tutorvista.com/…/…ansport-chain.php
