Question

question 3 of 10
which is a reactant in the process powered by sunlight hitting photosystem ii?
a. atp
b. nadph
c. adp
d. nadp+

Explanation:

When sunlight hits photosystem II, it powers the light - dependent reactions. ADP (adenosine diphosphate) is a reactant in the phosphorylation process (where ATP is synthesized). ATP is a product of these reactions. NADPH is formed in the electron transport chain (related to photosystem I in some aspects of its formation). NADP⁺ is involved in the formation of NADPH (but in a different part of the light - dependent reactions compared to the direct process powered by photosystem II light absorption for the reaction where ADP is a reactant).

Answer:

C. ADP
