Question

should water (h₂o) be included in the model as a reactant or product? if so, how should it be included?
a. yes, as reactant a.
b. yes, as product b.
c. yes, as reactant c.
d. no, it should not be included.

Explanation:

In photosynthesis, water (\(H_2O\)) is a reactant in the light - dependent reactions (part of the photosynthetic process shown in the chloroplast model). Reactant A is where water would enter as a reactant for the light - dependent reactions (e.g., for splitting to release electrons, protons, and oxygen). So water should be included as reactant A.

Answer:

A. Yes, as reactant A.
