Which of the Following Statements About Photophosphorylation is FALSE

Question

Which of the following statements about photophosphorylation is FALSE?
A)Light liberates an electron from chlorophyll.
B)The oxidation of carrier molecules releases energy.
C)Energy from oxidation reactions is used to generate ATP from ADP.
D)It requires CO₂.
E)It occurs in photosynthesizing cells.

Accepted Answer

Photophosphorylation does not require CO₂. It is a process of generating ATP in photosynthesizing cells using the energy from the light reaction and the oxidation of carrier molecules. A is true as the chlorophyll molecule absorbs light energy and liberates an electron, B is true as the oxidation of carrier molecules releases energy that drives ATP synthesis, and C is true as the energy released from oxidation reactions is used to generate ATP from ADP. E is also true as photophosphorylation occurs in photosynthesizing cells.
