Question

Which of the following statements is true?

A. Inside the cell the quantity of positively charged ions is greater than the
quantity of negatively charged ions.
B. Inside the cell the quantity of positively charged ions is less than the quantity
of negatively charged ions.
C. Inside the cell the quantity of positively charged ions is almost exactly equal to
the quantity of negatively charged ions.

Answer 1

Inside the cell, the quantity of positively charged ions is greater than the quantity of negatively charged ions. This is due to the active transport of ions across the cell membrane. For example, the sodium-potassium pump uses ATP to pump three sodium ions out of the cell for every two potassium ions it pumps into the cell.

Step-by-step explanation:

Inside the cell, the quantity of positively charged ions is greater than the quantity of negatively charged ions. This is due to the active transport of ions across the cell membrane. For example, the sodium-potassium pump uses ATP to pump three sodium ions out of the cell for every two potassium ions it pumps into the cell. This results in a net loss of positive charges from the cell, making the inside of the cell more negative compared to the outside.

For example, the sodium-potassium pump uses ATP to pump three sodium ions out of the cell for every two potassium ions it pumps into the cell. Therefore, option A is the correct statement: Inside the cell, the quantity of positively charged ions is greater than the quantity of negatively charged ions.
