What must happen when a concentration gradient is eliminated?
When a concentration gradient is eliminated, there will be no difference in the concentration of a substance across a region. This can lead to equilibrium, where molecules are evenly distributed, or in the case of active transport, energy may be required to maintain the concentration gradient.
How does a cell maintain differences in concentration of certain ions on either side of the plasma membrane?
Cells maintain unequal concentrations of ions on opposite sides of a cell membrane through active transport.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
Why does urine volume decrease as the gradient concentration increases?
As the concentration gradient increases, more water is reabsorbed by the kidneys, leading to concentrated urine with lower volume. This allows the body to conserve water and maintain proper electrolyte balance.
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.

Higher concentration is maintained by the process of?
active transport, where energy is used to move molecules against their concentration gradient to maintain a higher concentration in a particular area. This process is essential for cell functioning and maintaining homeostasis in living organisms.
How does a cell maintain differences in concentration of certain ions on either side of the plasma membrane?
Cells maintain unequal concentrations of ions on opposite sides of a cell membrane through active transport.
Why do multi cellular organisms need a ventilation system?
A ventilation system is needed in order to obtain oxygen for living organisms and to get rid of carbon dioxide. Surface diffusion utilized by many smaller organisms is not sufficient in supplying the oxygen needs of the body. It is also needed to maintain a concentration gradient in the alveoli.

When a cell membrane protein moves a solute in the opposite direction as the concentration gradient?
The process is known as active transport. It requires energy in the form of ATP to pump the solute against its concentration gradient. This allows the cell to maintain internal concentrations different from its external environment.
To maintain solute concentration gradient in the renal medulla what is required?
active transport of sodium and chloride ions from the ascending limb of the loop of Henle.
What type of transport do the hydrogen ion pumps use?
Hydrogen ion pumps primarily use active transport to move hydrogen ions (H+) across a membrane against their concentration gradient. This process requires energy, typically derived from ATP hydrolysis or, in some cases, from the electrochemical gradient of other ions. Active transport allows these pumps to maintain specific ion concentrations essential for various cellular functions, including pH regulation and membrane potential.
In order for molecules to move against the concentration gradient?
Molecules can move against the concentration gradient through active transport, which requires energy input from ATP or an electrochemical gradient. In active transport, specific proteins pump molecules across the cell membrane, consuming energy to maintain a concentration gradient.
How do fluid materials transport through membrane osmosis osmosis?
Fluid materials transport through membrane osmosis by the movement of water molecules across a semipermeable membrane from an area of higher concentration to an area of lower concentration. This process is driven by the concentration gradient of solutes on either side of the membrane. Osmosis helps maintain the balance of fluids and electrolytes in living organisms.
