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: -Energy released in the electron transport chain is captured as a proton gradient, which powers production of ATP by a membrane protein called ATP synthase. This process is known as oxidative phosphorylation.
Detailed explanation-3: -Key Takeaways: Electron Transport Chain The accumulation of protons in the intermembrane space creates an electrochemical gradient that causes protons to flow down the gradient and back into the matrix through ATP synthase. This movement of protons provides the energy for the production of ATP.
Detailed explanation-4: -The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.
Detailed explanation-5: -The ETC Links Chemical Energy to H+ Pumping Out of the Mitochondria. The ETC consists of an array of proteins inserted in the inner mitochondrial membrane. The overall plan is this: NADH delivers two electrons to a series of chemicals that differ in their chemical affinity for these electrons (see Figure 2.10. 7).
