Question

As a general proxy the following is useful:
flow or flux or rate = conductance * difference in potential
where conductance is meant to mean the ease with which the flow can take place, and difference in potential the energy of two things.
Using this proxy which is FALSE:

A. In photosynthesis (flux) CO2 is taken up through the stomata into the leaf via diffusion. If the external CO2 concentration increases and leaf internal CO2 concentration is stable, then photosynthesis will increase.

B. Given a reaction between A to B. If reactant A increases in concentration then the reaction will predominantly increase the rate of conversion of B to A.

C. If a flow of an polar molecule (water) occurs slowly across a membrane, and then a pore for that molecule (aquaporin) is inserted in the membrane, then the flow will increase as the pore allows a greater conductance. This is the same as saying that the activation energy needed for the water to transit the membrane effectively decreased.

D. If the voltage increases in a power supply, then more current (flow of electrons) will occur through a simple circuit.
