Answer 1

ANSWER

• In the electron transport chain, NADH donates its electron to NADH dehydrogenase enzyme.

- Electron transport chain

The electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer across a membrane with the transfer of protons (H⁺ions) .

• The electron transport chain is a system of molecules through which electrons are transferred to generate ATP
• The electron transport chain posses a major role in both photosynthesis and cellular respiration.
• The flow of electrons are EXERGONIC process.
• The energy stored from the glycolysis such as NADH and FADH is used by the electron transport chain to pump protons into the inter membrane space and generate a electrochemical gradient over the inner mitochrondrial membrane.
