How does the concentration gradient affect osmosis?
The concentration gradient in osmosis refers to the difference in solute concentration between two solutions separated by a semi-permeable membrane. Water will move from an area of low solute concentration to an area of high solute concentration in an attempt to equalize the concentration on both sides of the membrane. The steeper the concentration gradient, the faster the rate of osmosis.
Does osmosis go with the concentration gradient?
Yes, osmosis involves the movement of water molecules across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. This movement occurs in response to the concentration gradient of water molecules.
Can entropy effect osmosis?
Entropy itself does not directly affect osmosis. In osmosis, the movement of solvent molecules across a semi-permeable membrane is driven by a concentration gradient, not entropy. Entropy is a measure of disorder in a system and is related to the randomness of molecular movement.
What control osmosis?
Osmosis is mainly controlled by the concentration gradient of solute particles across a semi-permeable membrane. The direction of osmosis is from a region of lower solute concentration to a region of higher solute concentration, in order to balance out the concentrations on either side of the membrane. The movement of water during osmosis helps to equalize the concentrations of solutes on both sides of the membrane.
Osmosis is what type of transport?
Osmosis is a passive transport process where water molecules move across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. It does not require energy input from the cell.

Yes, osmosis involves the movement of water molecules across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. This movement occurs in response to the concentration gradient of water molecules.
Why does active transport require more energy than osmosis or faciliated diffusion?
Active transport requires more energy because it moves molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration. This process requires the cell to expend energy in the form of ATP to drive the movement of molecules through protein pumps. In contrast, osmosis and facilitated diffusion move molecules down their concentration gradient, requiring less energy.
Why is energy needed for transport?
Molecules are moving against a 'concentration' gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.
What is the relationship between osmosis and active transplant?
Osmosis is the passive movement of water through a semi-permeable membrane, while active transport is the movement of molecules across a membrane against their concentration gradient with the help of energy. In osmosis, water moves from an area of low solute concentration to high solute concentration, while active transport requires energy to move molecules against their concentration gradient.
What two ways could you expect the movement of water into a cell by osmosis to be similar to the diffusion of oxygen?
Both osmosis and diffusion of oxygen are passive processes that occur from areas of high concentration to areas of low concentration. Additionally, both processes are influenced by the concentration gradient of the substances involved.
What factor determines the direction of diffusion?
The concentration gradient for that substance determines the direction of net movement of molecules in passive transport.For example:When the concentration is high or that substance, it would move from the higher concentration to a lower concentration. And vice versa.
What factors determines the osmosis of a cell?
The factors that determine the osmosis of a cell include the concentration gradient of solutes inside and outside the cell, the permeability of the cell membrane to water, and the pressure exerted on the cell membrane. Osmosis occurs when water moves across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires energy because it involves the movement of molecules or ions against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires the use of cellular energy in the form of ATP to drive the transport proteins. In contrast, osmosis and facilitated diffusion occur naturally down the concentration gradient, so they do not require additional energy input.
When there are different amounts of a substance on either side of the cell membrane an gradient results?
osmosis
How did those substances go into the water outside the dialysis?
The substance moved into the water through osmosis. The concentration of the substances inside the dialysis bag was higher than in the water and membrane was permeable to the substances. As such, they moved from a high to a low concentration along a concentration gradient.
What is formed when enzymes move hydrogen ions across a membrane to an area of greater concentration?
A proton gradient is formed when enzymes transport hydrogen ions across a membrane, creating a difference in concentration between the two sides. This gradient can then be used to drive other cellular processes such as ATP production or transport of molecules across the membrane.
