∙ 16y agoIn 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.
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?
It tends to eliminate local concentration gradients.
Substances tend to move according to their concentration gradients by the process of?
Process of diffusion. Called osmosis for the process with water.
How do concentration gradients work?
i surpose if you have something to fiddle with then youue will be able to concentrate mre x xxxxxxxxxxxxxxxxxxxxxxxxxx jelly_bean xxxxxxxxxxxxxxxxxxxxxxxx
What concentration gradients are established and maintained by the sodium-potassium exchange pump?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm

How are concentration gradients maintained for diffusion?
Passive transports such as diffusion and osmosis move down their concentration gradients.
What are concentration gradients?
Concentration gradients is a solutes. This is used in the body.
In what direction do particles natural diffuse?
Down concentration gradients.
How are the concentration gradients in the alveoli maintained?
The heart is constantly pumping blood around the body. blood entering the lungs is deoxygenated and high in C02 The air in the alveoli has a high oxygen concentration and in comparison is low in C02 This sets up a concentration gradient. This causes oxygen to diffuse into the RBC and C02 to diffuse out in order to try balance the concentration. This balance is maintained by breathing, taking away the C02 in the lungs and bringing in fresh O2 and the constant pumping of blood, bringing more deoxygeneate blood into the lungs
What is the pumping of materials across a membrane against their concentration gradients?
Active Transport
Why would a cell need active transport?
To transport protein to specific areas of the cell, e.g. the synaptic terminal of a neuron's axon; and to transport ions & chemicals against their concentration gradients
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.
Which process uses proteins to move molecules against a concentration gradients?
active transport
Do greatest changes in weight occur in cells with steepest concentration gradients?
Yes, it does. Because the rate and the concentration are equally related, the biggest the difference in concentration the grater the rate of change of this concentration (osmosis)
Diffusion is important in body fluids because it tends to?
It tends to eliminate local concentration gradients.
