Which of the Following Processes is Most Directly Driven by Light

Question

Which of the following processes is most directly driven by light energy?
A) creation of a pH gradient by pumping protons across the thylakoid membrane
B) carbon fixation in the stroma
C) reduction of NADP+ molecules
D) oxidation of chlorophyll molecules

Accepted Answer

The oxidation of chlorophyll molecules is most directly driven by light energy, as light absorption by chlorophyll leads to the excitation of its electrons, initiating the photosynthetic process.
