What’s the role of oxygen in cellular respiration?

A.
It accepts electrons and keeps the electron transport chain running.
B.
It breaks down carbon-based sugar molecules to release energy and forms carbon dioxide.
C.
It combines with hydrogen ions in sugar molecules to release energy and form water.
D.
It supplies electrons to the electron transport chain to keep it running.

C.

It combines with hydrogen ions in sugar molecules to release energy and form water.

Explanation:

I think sorry if I'm wrong.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
