Question

photosynthesis: energy conversion quick check
which molecule is a high - energy output of the light reactions? (1 point)
oxygen
adp
atp
hydrogen

Explanation:

In the light reactions of photosynthesis, light energy is used to produce high - energy molecules. ATP (adenosine triphosphate) is a key high - energy output. Oxygen is a by - product (not the high - energy output in the context of energy - rich molecules for the plant's further use). ADP (adenosine diphosphate) is a reactant that gets phosphorylated to form ATP. Hydrogen (in the form of NADPH) is also produced, but the question asks for the molecule that is a high - energy output in terms of the energy - carrying phosphate bonds like in ATP.

Answer:

ATP
