Question

multiple choice question
at photosystem ii, the splitting of water by an enzyme embedded with manganese atoms results in the release of

○ nadph.

○ chlorophyll a.

○ oxygen.

○ atp.

Explanation:

In photosystem II, the water - splitting complex (with an enzyme embedded with manganese atoms) splits water molecules. The reaction of water splitting is $2H_2O
ightarrow4H^ + + 4e^-+O_2$. So this process results in the release of oxygen. NADPH is produced in the light - dependent reactions but not from water splitting at photosystem II. Chlorophyll a is a pigment involved in light absorption, not a product of water splitting. ATP is produced by chemiosmosis in the light - dependent reactions, not directly from water splitting at photosystem II.

Answer:

C. oxygen
