Muscle Physiology 3: Sodium-Potassium Pump

The video explains the sodium potassium pump, also known as sodium potassium ATPase, which pumps sodium and potassium ions across cell membranes. It details the enzymatic role of ATPase in hydrolyzing ATP to ADP and phosphate, and describes the pump's function in muscle and neuron physiology. The mechanism involves moving sodium ions out and potassium ions into the cell, driven by ATP hydrolysis. The pump's cycle is crucial for maintaining ion balance and enabling action potentials.

What is the significance of the sodium potassium pump being classified as an ATPase?

How does the sodium potassium pump contribute to the generation of action potentials in neurons?

Describe the role of aspartate in the function of the sodium potassium pump.
