For every hydrolyzed ATP molecule, are pumped out of the cell and are pumped into the cell with the sodium-potassium pump.

1

How does the sodium-potassium pump regulate normal cell volume and pressure?

1

Neutral amino acids are taken up in many cells by secondary active transport. The transporter involved transports Na+ down its electrochemical gradient into the cytosol, and the energy released by this _ transport is used to transport the amino acid into the cell ___ a concentration gradient.
