Sentences with phrase «osmotic gradients»

Because it means water absorption is heavily dependent on osmotic gradients - if the gut is filled with large quantities of mineral ions (particularly sodium), free glucose, etc., water will remain in the gut to serve as a buffer.

This action is sufficient to overcome the hydrostatic force of the water column — and the osmotic gradient in cases where soil water levels are low.

As blood glucose levels increase, glucose also increases within the aqueous humor, glucose readily diffuses across the lens capsule, an aldose reductase pathway converts glucose to sorbitol, sorbitol accumulates within the lens as it can not diffuse through lens cell membranes, the osmotic gradient increases, water enters the lens and irreversibly changes the lens structure via lens fiber swelling and rupture, vacuole formation, and clinically evident cataract.

Not exact matches

As water is lost out of the leaf cells through transpiration, a gradient is established whereby the movement of water out of the cell raises its osmotic concentration and, therefore, its suction pressure.

Biophysics also grew out of investigations on diffusion gradients and osmotic pressure — two forces responsible for the passive flow of matter in living organisms.
