Question

What are the end products of the electron transport chain?

Answer 1

The end products of electron transport chain are:

Water

Adenosine triphosphate (ATP)

Explanation:

• Most of the free energy released during the oxidation of  glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
• Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
• These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.

• The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP
