JudyIn order for sodium and potassium ions to enter and exit the cell, they have to be transported with the help of a transporter located on the cell membrane. This transporter requires ATP molecules to function. Essentially, the ATP molecules acts are fuel for the functioning of the sodium-potassium transporter. And thus, the involvement of ATP in maintaining sodium and potassium gradients across the cell membrane is explained.

How are concentration gradients maintained for diffusion?
Passive transports such as diffusion and osmosis move down their concentration gradients.
How do you establish a concentration gradient in anatomy?
In anatomy, a concentration gradient is typically established by the movement of substances from an area of higher concentration to an area of lower concentration. This can occur through processes like passive diffusion, active transport, or facilitated diffusion. Cells may also actively pump substances in or out to create and maintain concentration gradients.
Is there Concentration in Passive Transport?
No, concentration gradients are not actively created or maintained in passive transport. Instead, passive transport relies on the natural movement of molecules from an area of high concentration to an area of low concentration to occur spontaneously and without the input of additional energy.
What are osmotic gradients?
When water flows from areas of high concentration to areas of low concentration through semi-permeable membranes; down it'd concentration gradient.
Diffusion is important in body fluids because it tends to?
equalize concentration gradients, allowing for the movement of molecules from areas of high concentration to low concentration. This process is crucial for maintaining proper balance of nutrients and waste products in body fluids, ensuring proper cell function.
