In this equation for photosynthesis, where does the second reactant come from and what happens to it in the photosynthesis process? 6co + 6h o --> c h o + 6o 2 2 6 12 6 2 a. carbon dioxide comes from air and is broke down in the calvin cycle b. water is split to drive nadp to nadph conversion, and it is formed in the calvin cycle c. glucose is formed right after the calvin cycle d. oxygen is released as a gas after water is split answer asap! giving out !

The right answer is C - Oxygen is released as a gas after water is split.

The second reactant here is H2O (water), and it reacts during electron transport chain of chloroplast.

In chloroplasts, light is used to oxidize water to oxygen, and to reduce NADP + to NADPH on the other hand, with concomitant proton injection into the lumen of thylakoids. In the mitochondria, oxygen is reduced to water while NADH is oxidized to NAD + and the succinate is converted to fumarate, with concomitant expulsion of protons out of the mitochondrial matrix.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
