Hello 102683Moreno, <span>Where does the energy come from to make ATP in the light reaction, </span><span>from the motion of hydrogen ions.</span>
d. They can be concentrated in an organism’s fat tissues.
This is referred to as biomagnification -- the POPs become more concentrated as they move from one animal to another. This is a main concern because even trace amounts, in animals at the bottom of the food chain, can cause toxicity to animals at the top of the food chain.
Answer:
VDF= Vm- Veq.
Where VDF = Electrochemicall driving force
Vm=Membrane potential
Veq.=Equilibrium potential for the ion of interest
Ideally when VDF=0 at Electrochemical equilibrium, i.e. Vm=Veq, there is no net movement of ions across the membrane.
So, Answer is (D) This scenario is impossible.
