Question

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? 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.

Answer 1

Answer:

B

Explanation:

The energy source is ATP from light-dependent reactions.

Answer 2

Answer:

B. The energy source is ATP from the light-dependent reactions.

Explanation:

Photosynthesis is a biological process extremely responsible for the existence of life on earth. This is the biological process of greatest importance and relevance on our planet.

Photosynthesis occurs in two phases, a light-dependent phase and a light-independent phase. The light-dependent phase occurs in the thylakoid membrane and is responsible for transforming light energy into chemical energy by creating ATP molecules, which will provide energy for the next phase.

The independent light phase, in turn, occurs in the chloroplast stroma and is responsible for the carbon fixation reactions, carried out with the ATP energy generated in the light phase.
