What Happens First After Chlorophyll Absorbs Light Energy

Question

What happens first after chlorophyll absorbs light energy?
A) Water splits into H⁺ and O₂.
B) Hydrogen ions combine with electrons to produce NADPH.
C) Electrons are released and move to a higher energy level.
D) Carbon dioxide is converted to sugar.

Accepted Answer

When chlorophyll absorbs light energy, electrons in the molecule become excited and move to a higher energy level. This initial step is known as photoexcitation and is the first step in the light-dependent reactions of photosynthesis.

Note: Options A, B, and D are part of the overall process of photosynthesis but do not directly follow the absorption of light energy by chlorophyll.
