What is the source of energy used to power the sodium-potassium pump?

### The source of energy used to power the sodium-potassium pump is the breakdown of ATP.

## Step1: Identify the function of the sodium-potassium pump### The sodium-potassium pump is a type of active transport mechanism in cells that moves sodium ions (Na+) out of the cell and potassium ions (K+) into the cell. This process helps maintain the resting potential of the cell and is crucial for nerve impulse transmission and muscle contraction.## Step2: Recognize the energy requirement for active transport### Active transport processes require energy because they move ions against their concentration gradients, from an area of lower concentration to an area of higher concentration.## Step3: Determine the energy source for the sodium-potassium pump### The energy required for the sodium-potassium pump to function is derived from the breakdown of adenosine triphosphate (ATP). ATP is hydrolyzed to ADP (adenosine diphosphate) and an inorganic phosphate, releasing energy in the process, which is then used to power the pump.
