Consider the combustion of fuel and the analogous reaction the food undergoes as part of the metabolic processes:
fuel/food + O2(g) → CO2(g) + H2O(l)
The reverse of this reaction that occurs during photosynthesis is also pretty important:
CO2(g) + H2O(l) → fuel/food + O2(g)
Is this reaction endothermic or exothermic? Explain your reasoning.
