Question

Is photosynthesis endothermic or exothermic, why?

A. Endothermoc, energy is needed to oxidize water so it can eventually be stored in sugars. Free energy is temperature dependent.
B. Exothermic, energy is needed to oxide water so it can eventually be stored in sugars. Free energy is not temperature dependent.
C. Endothermic, energy is needed to oxidize water so it can eventually be stored in sugars. Free energy is not temperature dependent.
D. Exothermic, energy is needed to reduce water so it can eventually be stored in sugars.
E. Exothermic, energy is needed to oxidize water so it can eventually be stored in sugars.
F. Exothermic, energy is needed to oxidize water so it can eventually be stored in sugars. Free energy is temperature dependent.
G. Endothermic, energy is needed to reduce water so it can eventually be stored in sugars.

    Answer: I think A is right

    Explanation: Photosynthesis needs light so it is endothermic,

    Oxygen in water is oxidised and Oxygen is released in process.

    Free energy is temperature dependent. But also Carbo dioxide

    involves reaction. You needs to find out Calvin-Benson cycle
