Question

select the correct answer.
in photosynthesis, what gives energy to the electron moving through the electron transport chain?
a. water
b. nadph
c. light
d. atp

Explanation:

In photosynthesis, during the light - dependent reactions, light energy is absorbed by chlorophyll. This absorbed light energy excites electrons, giving them the energy to move through the electron transport chain. Water is split to provide electrons, NADPH is a product of the electron transport chain and light - dependent reactions (it carries electrons and hydrogen), and ATP is also a product of the light - dependent reactions (it stores energy). So the substance that gives energy to the electron moving through the electron transport chain is light.

Answer:

C. light
