Answer:
It is. (It is a lot for a hypothesis)
Step-by-step explanation:
Cellular respiration is backwards (C6 H12 O6 + 6 O2 --> 6 CO2+ 6 H2O + Energy). Here, glucose and oxygen are the reactants. With photosynthesis, glucose and oxygen would be the products. Same thing with the products of cellular respiration. Carbon dioxide and water are the products of cellular respiration, while they are the reactants in photosynthesis.
