Does respiration require energy

Yes, respiration does require energy

Explanation:

The electron carriers of cellular respiration - nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) -will pick up the high-energy electrons and forms NADH and FADH2.

The NADH and the FADH2 molecules carry these high-energy electrons and releases to the electron transport chain system. This system transfers these electrons from a donor to a receptor through redox reactions

Energy or ATP is required to initiate glycolysis process of respiration.

The glycolysis process of the respiration requires energy stored in these electrons to break glucose and convert it into carbon dioxide, water and energy or ATP molecules.
