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?
Osmosis is the process of water moving from an area of low solute concentration to an area of high solute concentration through a selectively permeable membrane. This movement occurs to equalize the concentration of solutes 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?
Osmosis is a special type of diffusion that involves the movement of water molecules across a selectively permeable membrane. It occurs when there is a difference in solute concentration on either side of the membrane, resulting in the movement of water to balance the concentration gradient.
What is the opposite of osmosis?
The opposite of osmosis is dialysis, which involves removing waste and excess substances from the blood by passing it through a membrane. In dialysis, solutes move from an area of high concentration to low concentration rather than water moving through a semi-permeable membrane like in osmosis.
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?
Passive transport of water by diffusion is the movement of water molecules across a membrane from an area of higher concentration to an area of lower concentration, without the use of energy. This process occurs through specialized channels called aquaporins, which allow water to move freely across the cell membrane.
What is the relationship for diffusion and osmosis?
Diffusion is the movement of molecules from an area of high concentration to low concentration, while osmosis is the diffusion of water molecules across a selectively permeable membrane. Osmosis is a specific type of diffusion that involves water molecules moving to balance the concentration of solutes on either side of the membrane.
