MUSCLE PHYSIOLOGY

Detailed explanation-1: –The electron transport system takes place in the cristae present in the inner membrane of the mitochondria. Cristae are the infoldings of the inner membrane of the mitochondria and it aids in the cellular respiration.

Detailed explanation-2: -Briefly, the ETC is a series of enzymes found within the inner mitochondrial membrane that transfers electrons from donor to acceptor proteins through several redox reactions. This process is ultimately driven by oxygen, the final electron acceptor.

Detailed explanation-3: -The mitochondrial cristae are where electrons are passed through the electron transport chain, which pumps protons to power the production of energy molecules called ATP. NADH and FADH2 are molecules that carry electrons.

Detailed explanation-4: -The ETS is a series of electron carriers embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular O2. In this process, protons are pumped from the mitochondrial matrix to the intermembrane space.

Detailed explanation-5: -The ETC is a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy.
