Which process is most directly driven by light energy?
a) creation of a ph gradient by pumping protons across the thylakoid membrane
b) carbon fixation in the stroma
c) reduction of nadp⁺ molecules
d) removal of electrons from chlorophyll molecules
e) atp synthesis

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.

Ithink the answer is c. i’m not sure though i’ll notify you when i have an exact answer!
