6. What happens as electrons move along the chain of
molecules known as the
electron transport chain?

A They lose energy, which is then used to break down ATP.

B They lose energy, which is then used by the cell to make ATP.

C They gain energy, which causes ATP molecules to lose phosphate
Froups.

D They gain energy, which causes Htions to join with oxygen to produce
water.​

Answer:

B.

Explanation:

ETS or electron transport chain is the last stage of aerobic cellular respiration that leads to the formation of a huge amount of adenosine triphosphate also known as ATP which is the energy currency of the cell.  

It occurs in the inner mitochondrial membrane. Electrons are passed through various protein complexes present in the inner membrane of mitochondria.  

As electrons pass through the electron transport chain, electrons move from a higher to a lower energy level and are ultimately passed to oxygen.

During this process, Energy release in the electron transport chain is trapped as a proton gradient. Due to this concentration gradient, ATP synthase is a final protein complex, forms ATP.

Answer is B I hope this helped
