Question

question 9 of 25
which molecule is split apart in photosystem ii?
a. glucose
b. atp
c. carbon dioxide
d. water

Explanation:

In photosystem II, water ($H_2O$) is split. This process, known as photolysis, releases oxygen ($O_2$), protons ($H^+$), and electrons. The electrons are used to replace those lost by chlorophyll a in the reaction center of photosystem II. Glucose is produced in the Calvin cycle. ATP is synthesized in the light - dependent reactions (but not split in photosystem II). Carbon dioxide is used in the Calvin cycle (not split in photosystem II).

Answer:

D. Water
