Detailed explanation-1: -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. The energy released forms a proton gradient, which is used in chemiosmosis to make a large amount of ATP by the protein ATP-synthase.

Detailed explanation-2: -The electron transport chains are on the inner membrane of the mitochondrion. As the high-energy electrons are transported along the chains, some of their energy is captured. This energy is used to pump hydrogen ions(from NADH and FADH2) across the inner membrane, from the matrix into the intermembrane space.

Detailed explanation-3: -The electron transport chain creates a proton gradient that ultimately leads to the production of a large amount of ATP.

Detailed explanation-4: -The electron transport chain is located on the inner membrane of the mitochondria. The electron transport cycle yields around 30-32 ATP molecules, according to current studies.

Detailed explanation-5: -In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
