Question

during the light - dependent reactions of photosynthesis, energy excites electrons in chlorophyll molecules, transforming the energy into chemical energy.
what provides the energy that excites the electrons in the chlorophyll molecules?
○ nadph
○ co₂
○ light
○ water
what is the source of the electrons that replace the excited electrons lost from chlorophyll?
○ nadph
○ co₂
○ water
○ light

Explanation:

In the light - dependent reactions of photosynthesis, light energy is absorbed by chlorophyll. This energy excites electrons in chlorophyll. Water is split during these reactions, and the electrons from water replace the excited electrons lost from chlorophyll.

Answer:

First question: C. light
Second question: C. water
