Consider the formula for glucose: C6H1206. In the processes of photosynthesis, what supplies the hydrogen (H) used in the formation of glucose?
Olight energy
carbon dioxide
O chlorophyll
water

Water, H2O

Explanation:

Formula for photosynthesis:

Water + Carbon dixoide = Glucose + oxygen

The answer is water. A process called photolysis takes place(H₂O->2H⁺,2e⁻,1/2O₂). The hydrogen is incorporated in a molecule called NADPH⁺(Nicodinamid dinucleotide-phosphate), which is then used in Calvin's cycle.
