The electron transport chain is a crucial process in cellular respiration, where electrons are passed along a series of proteins and molecules in the inner mitochondrial membrane to generate ATP, the cell's main energy source. This chain of reactions involves the transfer of electrons from electron donors to electron acceptors through a series of redox reactions, ultimately driving the synthesis of ATP through oxidative phosphorylation. The electron transport chain is essential for the production of energy in aerobic organisms and plays a central role in cellular metabolism. It is also a target for various drugs and toxins that can disrupt its function, leading to a variety of diseases and disorders.
