Which Process is Most Directly Driven by Light Energy

Question

Which process 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) removal of electrons from chlorophyll molecules
E) ATP synthesis

Accepted Answer

The removal of electrons from chlorophyll molecules is the process most directly driven by light energy. When chlorophyll absorbs light, it becomes excited and loses electrons, which is the initial step in the process of photosynthesis.
