multiple choice question
the electron leaving photosystem ii has ______ energy than the same electron as it enters photosystem i.

the same
less
more

Explanation:

In the light - dependent reactions of photosynthesis, electrons move from Photosystem II to Photosystem I through an electron transport chain. As electrons pass through the electron transport chain, they lose energy (this energy is used to pump protons and create a proton gradient for ATP synthesis). So the electron leaving Photosystem II has more energy than the same electron as it enters Photosystem I.
