| Fortunately it combines with the haemoglobin to form oxyhaemoglobin, thus maintaining a steep concentration gradient. |
|
| Steady-state diffusion of water along the two defined pathways depends on the concentration gradient and on the diffusivity of the substance. |
|
| Therefore, water tends to flow into the cell by osmosis, down its concentration gradient. |
|
| This produces a very reasonable strategy for chemotaxis, in which the bacterium follows the concentration gradient of one sugar alone. |
|
| The motive force is supplied by sodium or hydrogen ions flowing down a concentration gradient from the outside. |
|
| The concentration gradient of the material that is adsorbed is the driving force behind adsorption. |
|
| Thus, the flux of water vapour at a constant concentration gradient across pores of invariable geometry will depend only on the molecular characteristics of the gas. |
|
| The liquid flows down countercurrent to the cossettes and enriches with sugar due to the existing concentration gradient. |
|
| Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane. |
|
| Diffusion is a passive transport process driven by the concentration gradient at the G L interface. |
|
| Therefore, chemicals diffuse across the membrane only when a concentration gradient exists across the cell membrane. |
|
| This allows calcium ions to enter the nerve terminal along their concentration gradient. |
|
| Energy is consumed because the transport proceeds against the concentration gradient. |
|
| The extent of potassium loss depends on the concentration gradient across the tubule walls. |
|
| The organisms swim smoothly up the concentration gradient of an attractant and begin to accumulate in areas of high concentration of the attractant. |
|
| We propose a novel mechanism in human airway epithelia that generates a transepithelial glucose concentration gradient by expressing 2 distinct facilitated diffusion transporters in polarized localizations. |
|
| Studies with Voltaren Emulgel demonstrated that the drug is efficacious in a variety of animal models of inflammation and that it is absorbed topically with a significant concentration gradient favouring local tissues. |
|
| These proteins transport their substrates at the expense of ATP against a steep concentration gradient and protect the liver cell from the toxic effects of high concentrations of their substrates. |
|
| As the driving substrate is transported down its concentration gradient, it drags with it the driven substrate, which is forced to move up its concentration gradient. |
|
| Via a concentration gradient, they act like thin selective barriers used in a variety of sectors from the agro-food industry to the treatment of waste water and water purification. |
|
|
|
| The concentration gradient between water and the solution causes the salt ions to move out of the U-tube through the capillaries into the demineralised water. |
|
| Alveolar-arterial oxygen concentration gradient. |
|
| Thus, a concentration gradient of protons builds up. |
|
| Osmosis only depends on the concentration gradient. |
|
| When matter is transferred from one phase to another across a gas-liquid interface, a concentration gradient will occur in each phase because of a resistance. |
|
| A concentration gradient exists in the effluent, so that the effluent concentrations in the centre of the plume are larger than those toward the plume edges. |
|
| Optical component with nanoscale particles embedded in a solid matrix, characterized by a gradient structure, in which there is a concentration gradient os said nanoscale particles. |
|
| Seawater flows tangentially along the membrane, creating an salt concentration gradient along the membranes length, the last element having the most concentrated brine bulk. |
|
| The concentration gradient is determined by the current density, the active anodic area size and the solvated metallization ions' diffusion velocity. |
|
| The ions transport through the fuel cell electrolytes under the influence of both electrical potential gradient and concentration gradient as the driving forces. |
|
| Gastropods may use odor-guided rheotaxis and move upstream after detection of attractive chemical cues until they are able to detect and follow a concentration gradient. |
