What is the process of water moving from a low solute concentration to a high solute concentration?
hypertonic
Where and when does osmosis occur?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane .
Which of these nephron transport processes does not show saturation at high solute values a. coupled cotransport b. facilitated diffusion c. active transport d. simple diffusion?
d. simple diffusion
Why is facilitated diffusion faster than simple diffusion?
Facillatated diffusion is faster than simple diffusion when solute concentration is low because it uses channels to transport molecules throught the lipid bilayer. Simple diffusion depends upon concentration gradients so the net movement of diffusing molecules depends on the concentration gradient, thus the rate of diffusion is directly proportional to the concentration gradient. Simple diffusion is also a type of passive transport, which requires no energy input, whereas facilitated diffusion is protein mediated transport. Passive diffusion of solute into a cell is linearly related to the concentration of solute outside the cell. Carrier proteins increase the rate of diffusion by allowing more solute to enter the cell. Facilitated diffusion, however, approaches a maximum rate as the carrier proteins become saturated with solute.
Osmosis is a type of what process?
Osmosis is the diffusion of water or another solvent from a more dilute solution (of a solute) to a more concentrated solution (of the solute) through a membrane that is permeable to the solvent.
What is simple diffusion of water through a membrane called?
Osmosis is the term for the diffusion of solute through a membrane from a place of higher concentration to a place of lower concentration. The process of osmosis will continue until the concentration is equal on both sides of the membrane.
What is the diffusion of water into and out of a membrane?
This is called osmosis, which is the movement of water from a low solute concentration to a high solute concentration.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
What is the special type of diffusion where the solute passes through a selectively permeable membrane?
Osmosis
What is the process of water moving from a low solute concentration to a high solute concentration?
hypertonic
How does osmosis happen?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane
Where and when does osmosis occur?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane .
Osmosis is a type of diffusion?
Yes. Osmosis is a type of diffusion involving the movement of water through a semipermeable membrane from a solution with a low solute concentration to a solution with a high solute concentration, until the concentration of fluids on both sides of the membrane is equivalent.
What is the opposite of osmosis?
Because diffusion is the movement of solute particles while osmosis is the movement of solvent molecules through a semipermeable membrane.
Which of these nephron transport processes does not show saturation at high solute values a. coupled cotransport b. facilitated diffusion c. active transport d. simple diffusion?
d. simple diffusion
What is a passive tranport of water by diffusion?
Osmosis is the movement of water across a membrane so there will be an equal concentration of solute and water on both sides of the membrane.
What is the relationship for diffusion and osmosis?
Diffusion is a process in which solute molecules move from higher concentration towards lower concentration. While in case of Osmosis, the water moves towards highest solute concentration in a semi-permeable membrane.
