When ADP gains a phosphate to form ATP, A.free energy is released by the loss of a phosphate. B.energy is consumed. C.the reaction ends. D.chemical energy is converted to light energy. E.ribose loses an oxygen to become deoxyribose.

B.energy is consumed.

Explanation:

When ATP gain phosphate the energy is consumed(ADP+ Pi+ free energy→ ATP+ H2O). So in the formation of ATP energy is used and consumed  and that energy is stored in the terminal phosphate bond.

This ATP act as the cellular form of energy and this energy is released when the terminal phosphate bond breaks and terminal phosphate is released from the ATP. This energy is used to perform the metabolic function required for cell survival and cell growth. Therefore energy is consumed in ATP formation.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
