Question:
Hi. I was wondering, how much energy is required to make one glucose molecule in photosynthesis?


Replies:
Since a mole of glucose (180 grams) releases 283 Kcal of energy when it is metabolized, it takes at least this much energy to synthesize it during photosynthesis. One molecule would require 283 Kcal divided by Avogadro's number (6.023 x 10e23).
