Which of the following can combine in a cell to convert a lower-energy molecule into a higher-energy molecule? ADP + P + energy ATP + P + energy ADP + P ATP + P

ADP + P + energy

Explanation:

Adenosine triphosphate (ATP) is used as energy source in endergonic (Energy absorbing) reactions in body. As the name indicates It consists of a ribose sugar, adenine base and phosphate group.

ADP is adenosine dinucleotide so the difference between ATP and ADP is of phosphate group. In ADP there are two phosphate groups and in ATP there are three phosphate groups. These phsosphate groups are linked to each other by covalent bond which capture or release the energy.

ADP and inorganic phosphate in the presence of energy (usually occur in light reactions) combined to form ATP. These ATP are used in dark reaction to combine carbon molecule (Carbohydrate production) and produce ADP + inorganic phoshate.

the answer would be b
