Major biology help :(
Hey guys I really need your help :confused:
So I have two questions that I have to complete. And they really make me confused.
the first is : The molecule that precedes the electron transport chains of both photosystem I and photosystem II is an electron acceptor.
What is the original molecule that is the electron donor for both of these systems?
and the second it : Explain how the light reactions would be affected if there were no concentration gradient of protons across the thylakoid membrane.
Help is in need! :eek:
Thank you in advance. :D
