How does the concentration gradient affect osmosis?
Osmosis is a passive transport process. Therefore it can only go with the concentration gradient.
Osmosis is what type of transport?
Diffusion. It's the movement of water through a permeable membrane. And it's always passive.
Considering the meaning of osmosis explain how reverse osmosis would make more pure?
Using the tern osmosis means that water will diffuse from higher to lower concentration. Being that reverse osmosis mean a method of purifying water, reverse osmosis leaves the lower concentration to go to the higher concentrated environment to become pure. Did that make sense?
Is osmosis trans active?
Osmosis is a passive form of diffusion as it travels downa concentration gradiant, as opposed to active transport; a type of diffusion that can go against a conc. grad.
How are osmosis and diffusion similar and how are they different?
Osmosis is where the water or other particles go from an area of higher concentration to an area of lower concentration. This is often against a pressure gradient. This type of reaction involves a process known as ACTIVE TRANSPORT where ATP (adenotriphosphate) is required (energy required).Diffusion is where the products even themselves out through a given solution. This process is done by passive transport, where NO energy or ATP are required.Osmosis is diffusion through a semi-permeable membrane.
How does the concentration gradient affect osmosis?
Osmosis is a passive transport process. Therefore it can only go with the concentration gradient.
Why does active transport require more energy than osmosis or faciliated diffusion?
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
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 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?
There are a many factors which affect the rate of osmosis. One of the factors is the temperature of the solution and solvent. Temperature affects osmosis because when temperature goes higher, molecules move faster. So, osmosis will increase. If the temperature is decreased, the rate of osmosis will decrease too. Another factor which affects osmosis is the size of the particles. The size of the particles affect osmosis because osmosis is the movement of a solvent through a membrane and membrane's pores, or empty spaces, are different sizes. Only certain particles can fit through any given membrane. The concentration gradient can also affect osmosis because osmosis is a transport process therefore it can only go with the concentration gradient. The lower the concentration of the solute within a solvent, the faster that osmosis will occur into that solvent. The light and dark also affects osmosis because the greater the light, the faster osmosis occurs. The PH affects osmosis as well. The greater the pH of a solution, the more acidic or concentrated it becomes. The greater the concentration gradient of a substance on either side of a membrane the faster osmosis occurs.
When there are different amounts of a substance on either side of the cell membrane an gradient results?
osmosis
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
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 happens when concentration gradient 0?
When the concentration gradient is 0, no flow is allowed to go through the cell wall. To get motion through a membrane, the concentration gradient must be higher than 0.
Osmosis is what type of transport?
Diffusion. It's the movement of water through a permeable membrane. And it's always passive.
What direction are substances said to diffuse?
if something diffuses e.g. particles through the air or CO2 out of body cells means the particles go from a high concentration to a low concentration
What isit called when a molecule moves across a semipermeable membrane into a region of higher concentration?
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.
