What affects the rate of diffusions?

The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

What does diffusion rate depend on?

The diffusion rate depends on several factors: the concentration gradient (the increase or decrease in concentration from one point to another); the amount of surface area available for diffusion; and the distance the gas particles must travel.

What are the four factors that affect diffusion?

Several factors determine the rate of diffusion of a solute including the mass of solute, the temperature of the environment, the solvent density, concentration, and solubility.

What affects the rate of active transport?

The rate of active transport is affected by: The speed of individual carrier proteins - the faster they work, the faster the rate of active transport. The number of carrier proteins present - the more proteins there are, the faster the rate of active transport.

What factors affect the rate of osmotic movement of water?

The rate of osmosis varies with a number of factors, including temperature, pressure, and the difference in solute concentrations between two solutions separated by a selectively permeable membrane.

What affects osmosis and diffusion?

A number of factors can affect the rate of diffusion, including temperature, molecular weight, concentration gradient, electrical charge, and distance. Water can also move by the same mechanism. This diffusion of water is called osmosis.

How does size affect the rate of diffusion?

Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.

What affects the rate of diffusion quizlet?

the greater the difference in concentration, the more rapid th diffusion. The closer the distribution of the material get to equilibrium, the slower the rate of diffusion becomes. Higher temperature increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.

How does pressure affect diffusion rate?

As with any chemical reaction, increasing the temperature or pressure increases the kinetic energy of the particles, thus increasing the rate of diffusion.

How does the concentration gradient affect diffusion?

The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of diffusion is said to be 'down' or 'with' the concentration gradient. Diffusion stops when the concentration of the substance is equal in both areas.

What factors affect the rate of secondary active transport?

At low glucose concentration, there will be less production of energy leading to decreased rate of active transport. Rate of active transport increases with increase in glucose concentration due to increase in the rate of energy production. Temperature affects the enzyme controlled respiration process.

Does active transport go from low to high?

During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

How does surface area affect the rate of active transport?

The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

What is osmosis which factor affects osmosis in a cell?

Osmosis is movement of only water molecules through a semi permeable membrane from their region of higher concentration to their region of lower concentration. The factors that affect the rate of osmosis are concentration of cell sap, the flow time rate and temperature.

What affects osmotic pressure?

Osmotic pressure is affected by concentration and temperature. Concentration of solute and temperature each affect the amount of pressure created by the movement of water across a membrane. Higher concentrations and higher temperatures increase osmotic pressure.

Why does the rate of osmosis increase with concentration?

The concentration of a solute affects the rate of osmosis over time, in a way where, the higher the concentration of a solute, the faster the rate of osmosis. This happens because, in a semi-permeable membrane the water is the only through that can move through. ... That results in the rate of osmosis being faster.
