Question

All of the following are true about proton pumps involved in photosynthesis EXCEPT

that they:
a) move protons UP the concentration gradient across thylakoid membrane
b) require energy to operate
c) are powered DIRECTLY by capture of photons
d) are powered DIRECTLY by flow of electrons

Answer 1

Proton pumps involved in photosynthesis play a role in the light-dependent reactions and are directly powered by the capture of photons and the flow of electrons

Step-by-step explanation:

Proton pumps are involved in the process of photosynthesis, specifically in the light-dependent reactions that take place in the thylakoid membrane of the chloroplast. These pumps play a crucial role in the production of ATP (adenosine triphosphate) by actively transporting protons across the thylakoid membrane. However, all of the options provided in the question are actually true about proton pumps involved in photosynthesis. They move protons up the concentration gradient across the thylakoid membrane, require energy to operate, and are directly powered by the capture of photons and the flow of electrons.
