Question

which kind of reaction is photosynthesis? (1 point)
○ light-independent
○ endothermic
○ exothermic
○ temperature-independent

Explanation:

Photosynthesis absorbs energy (light) to convert CO₂ and H₂O to glucose, so it's endothermic (reactions that absorb heat/energy). Light - independent is part of photosynthesis, not the reaction type. Exothermic releases energy, and temperature - independent is incorrect as temperature affects it.

Answer:

B. endothermic
