Question

Do the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell?

Answer 1

Answer:

Yes.

Explanation:

Yes, the positive charges on both calcium ions and sodium ions will responsible for the movement of these ions into or out of the cell because the membrane has negative charge which attract these positively charged calcium ions and potassium ions. These difference concentrations of sodium and potassium in the cell are due to the activity of cell membrane active transport system which moves sodium out of the cell and potassium into it.

Answer 2

Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.

What do you mean by Diffusion?

Diffusion may be defined as a process resulting from the random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

The membrane of a cell possesses a negative charge, so it attracts these positive charge ions and makes a concentration difference that leads to the process of active transport through which sodium moves out of the cell and potassium into it.

Therefore, Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.
