Also known as ATP and is the basic molecule in which cells store and use energy.
Cellular respiration is the process by which the chemical energy of molecules is released and partially captured in the form of ATP(Adeninetriphosphate, a form of energy release). Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
The electron transport chain is the final stage of cellular respiration where electrons are passed along a series of protein complexes to generate ATP. As electrons move through the chain, protons are pumped across the inner mitochondrial membrane, creating a gradient. This gradient drives the synthesis of ATP through ATP synthase, producing the majority of ATP in cellular respiration.
