Question

Select the true statements about the electron transport chain.

a. The major reactants in the electron transport chain are O 2 and either NADH or FADH 2 .
b. The electron transport chain produces two ATP.
c. In the electron transport chain, a series of reactions moves electrons through carriers.
d. The electron transport chain is an anaerobic process.
e. Coenzyme Q and cytochrome c are components of the electron transport chain.

Answer 1

Answer: The true statements are option C. IN THE ELECTRON TRANSPORT CHAIN, A SERIES OF REACTIONS MOVES ELECTRONS THROUGH CARRIERS

And option E. COENZYME Q AND CYTOCHROME C ARE COMPONENTS OF THE ELECTRON TRANSPORT CHAIN.

Explanation: Electron transport chain occurs via a redox reaction across a membrane along with transfer of protons. There is a transfer of electrons from an electron donor to an electron acceptor in Electron transport chain.

This leads to the production of adenosine triphosphate (ATP) as a result of the energy produced when electrons from nicotinamide adenine dinucleotide (NADH) and Flavin adenine dinucleotide (FADH2) are passed to molecular oxygen.

Coenzyme Q and cytochrome c are components of the electron transport chain because they are the mobile carrier of the electrons.
