Question

what is the source of energy used to power the sodium - potassium pump?
multiple choice
formation of atp
potential energy in a concentration gradient
transport of atp by the pump
sunlight
b reakdown of atp

Explanation:

The sodium - potassium pump is an active - transport mechanism. It uses the energy from the breakdown of ATP (adenosine triphosphate). When ATP is hydrolyzed into ADP (adenosine diphosphate) and a phosphate group, energy is released which powers the pump to move sodium ions out of the cell and potassium ions into the cell against their concentration gradients.

Answer:

E. breakdown of ATP
