Question

Both the concentration gradient and the electrical gradient combine to form the ________________ gradient; this determines the movement of ions and other substances across the plasma membrane.

Answer 1

The electrochemical gradient is formed by the combination of the concentration gradient and the electrical gradient. It determines the movement of ions and other substances across the plasma membrane.

Step-by-step explanation:

The combination of the concentration gradient and the electrical gradient forms the electrochemical gradient. This gradient determines the movement of ions and other substances across the plasma membrane.
