During the light-independent reactions of photosynthesis, carbon dioxide is combined with hydrogen to form sugars. What is the energy source, if any, that allows this process to occur?

A. The energy source is high-energy bonds in sugar molecules.
B. The energy source is ATP from the light-dependent reactions.
C. The energy source is ATP from processes that occur in other organelles of the cell.
D. No energy source is used; the process occurs without an energy input.

Respuesta :

I believe the answer is A but I am not sure. Sorry.

Answer: Option B

Explanation:

Photosynthesis consists of light dependent reactions and light independent reaction. These reactions combinely leads to the formation of the carbohydrates and releasing oxygen into the atmosphere.

The Using the ATP and NADPH that is produced during the time of light-dependent reactions serves as the source of energy for the formation of carbohydrates in the cells.

Hence, the correct answer is option B
