Question

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

Explanation:

Photosynthesis requires energy input from sunlight. Endothermic reactions absorb energy. Exothermic reactions release energy. The light - dependent reactions use light energy and the light - independent reactions (Calvin cycle) use the energy carriers from the light - dependent reactions. Temperature can affect the rate of photosynthesis but it is not temperature - independent. Since it takes in energy, it is endothermic.

Answer:

endothermic
