Verified step by step guidance

Understand the primary function of the Na+/K+ pump: The Na+/K+ pump is an essential membrane protein that actively transports sodium (Na+) out of the cell and potassium (K+) into the cell, using ATP for energy. This process is crucial for maintaining the electrochemical gradient across the cell membrane.

Consider the role of the Na+/K+ pump in maintaining the resting membrane potential: The pump helps maintain the resting membrane potential by ensuring a higher concentration of Na+ outside the cell and a higher concentration of K+ inside the cell, which is vital for nerve impulse transmission.

Evaluate the role of the Na+/K+ pump in regulating cell volume: By controlling the movement of Na+ and K+ ions, the pump indirectly influences osmotic balance and cell volume, preventing cell swelling or shrinkage.

Examine the function of the Na+/K+ pump in generating heat in brown adipose tissue: The activity of the Na+/K+ pump can contribute to thermogenesis in brown adipose tissue, where energy from ATP hydrolysis is released as heat.

Identify the incorrect function: Facilitating the transport of glucose into cells is not a direct function of the Na+/K+ pump. Glucose transport typically involves other mechanisms, such as glucose transporters (GLUTs) or secondary active transport via symporters like the sodium-glucose linked transporter (SGLT).
