Plant cells?

anaise · Answer

If so, Number 4 would be the calvin cycle...

anaise · Answer

For number 3, ATP is created twice, or formed. It is ATP

anaise · Answer

For number 2, enzymes is your answer, I mean the Calvin cycle doesn't happen as fast as a bullet. So it is enzymes, I'm quite sure.

anaise · Answer

Do you know how photosystems work?

Hi, I have no idea how this website works but I will try anyway. 

Number 1:
I guess it would be answer A (enzymes) because the questions is about photosynthesis in my opineon. In this case the final enzyme that uses the electons gained from photosystem 1 would be Ferredoxin-NADP(+)-oxidoreductase.

Number 2:
The answer would be B, enzymes again. They mediate all the reduction oxidation reactions during the cycle.

Number 3:
It's B, the electron transport chain produces an proton gradient which can be used by ATPsynthase to catalyze ATP production.

Number 4:
It's D, non of the above. The final product of the cellular respiration would be CO2 or ATP or something like this. For the light dependent reaction, it would be ATP or NADPH.  Most misleading is answer C, the Calvin Cylve, however the final product of the calvin cycle is triose phosphate (Glyceraldehyde 3-phosphate), not glucose! Glucose is only gained by starch degreadtion in the night within plant cells.

I didn't see the point in explanation because the user hasn't been on.

But thanks for showing me my mistake, but still am unsure.
