Which term describes the difference in electrical charge across a membrane?

Resting potential

Explanation:

The resting potential is the term used to the describe the difference in electrical charge across a membrane. Ion is solution are capable of carrying a charge so their presence in biological systems is of interest. Two factors affect the resting potential:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

a is the correct answer
