What is the purpose of respiration? What are the inputs, products, and energy required or gained? How does it differ from fermentation? in other words, how do Glycolysis, Pyruvate dehydrogenase, Kreb cycle, and electron transport chain work and connect to the production of ATP by chemiosmosis? compare that to fermentation.
