Answer to Question #306386 in Electric Circuits for mela

Question

1.How would you define membrane potential?

2.What are the factors that could affect the ion movement?

3.If the membrane allows only positive charges to get through it,what happens to the concentration of both sides of the membrane?

4.From what you have learned in Biology,why is membrane potential essential among plants and animals?

Answer 1

Solution;

1.Membrane potential is a potential gradient that forces ions to passively move in one direction: positive ions are attracted by the 'negative' side of the membrane and negative ions by the 'positive' one.

2.The concentration gradient of the individual ionic species and the permeability of the membrane to the individual ionic species.

3.The concentrations on both sides of the membrane remain the same, but individual molecules still move back and forth.

4.Animals and plants require the breakdown of organic substances through cellular respiration to generate energy. This process, which produces ATP, is dependent on the electron transport chain.
