What intrinsic protein is responsible for maintaining the H ion gradient?
Proton pumps as well as ATP synthase operating in reverse maintain the hydrogen ion gradient of a cell.
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.
Do organisms always maintain the hydrogen ion concentration gradient?
Yes, without it there would not be enough energy to produce ATP.
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 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.
Are spacers necessary in heat exchanger?
because it maintain space between baffels
What Is The Purpose Of Countercurrent Flow In Dialysis?
Increased sodium and chloride ion concentrations in the interstitial fluid of the renal medulla is the result of countercurrent mechanisms

Yes, without it there would not be enough energy to produce ATP.
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 is the critical distance a cell must maintain from a capillary to survive?
The critical distance a cell must maintain from a capillary in order to survive is rarely greater than 40 to 200 µm. The role that diffusion plays in this process is that it can maintain the concentration gradient required at the cell.
What is the sodium potassium pump an example of?
The sodium potassium pump is an example of a type of ion transporter that operates via ATP. It is used to maintain the Na and K concentration gradient in cells.

How do you convert residential furnace to burn used deep fryer oil?
1) A GOOD FILTRATION SYSTEM, TO 5 MICRONS IS FIRST. 2) A TEMPERATURE CONTROLLED PRE-HEATER BLOCK TO MAINTAIN CONSISTANT VISCOSITY WOULD FOLLOW. 3) NOZZLE SIZING BASED ON MEASURED TEMPERATURE RISE ACROSS THE HEAT EXCHANGER WOULD, AT START-UP, MAINTAIN RATED BONNET CAPACITY WITHIN THE OEM SPECIFICATIONS. LC
What do news presenters read off?
News presenters typically read off a teleprompter, which displays the script or text of their news story. This helps them maintain eye contact with the camera while delivering accurate and timely information to their audience.
How refreshing the air in the air sacs helps to maintain a steep diffusion gradient?
It increases the partial pressure of oxygen, so the concentration is higher than that of the blood. Therefore the partial pressure of CO2 decreases , so Co2's concentration is lower than the bloods.
