Which of the following does not affect the rate of diffusion through a membrane?
The amount of energy available for transport molecules does not affect the rate of diffusion. This is because diffusion is a passive process.
Which of the following is not a reason why a solute would require facilitated diffusion?
The movement of a given solute usually occurs in both directions (into and out of the cell). Which of the following is NOT a reason why a solute would require facilitated diffusion? The solute directly requires ATP for its transport. The solute is too large to pass on its own.
What does not affect diffusion rate?
The factor that does not affect the rate of diffusion are the electrical charges of the diffusion particles. In a solution, the rate of diffusion gets affected by the presence of other particles, the solubility of diffusing particles in the lipids, the molecular size of the substances in the solution and more.
What factors do not affect the rate of diffusion?
Complete answer: The electrical charges of the diffusion particles are the only factor that does not have an effect on the rate at which diffusion occurs.
Why does albumin not diffuse into the dialysate?
The results were that half of the glucose diffused from the right beaker to the left beaker, following its concentration gradient; some water diffused from the right beaker to the left beaker because the left beaker had a higher solute concentration; and albumin did not move because it was too large to get through the …
Can You diffuse urea through a 20 MWCO membrane?
Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the 20 MWCO membrane because it does not ionize. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane.
How does na + ci diffuse through the 50 MWCO membrane?
The Na+CI- will diffuse through the 50 MWCO membrane but will not diffuse through the 20 MWCO membrane. So, adding more Na+CI- with the 20 MWCO membrane increased the osmotic pressure. Adding it to the 50 MWCO membrane did not result in any pressure whatsoever because it diffused through this membrane.
Why does the diffusion rate of urea increase?
Multiple factors affect the rate of diffusion. For example, diffusion rate increases as solute concentration increases, and diffusion rate increases as solute molecular weight decreases. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? a.
How does glucose diffuse through the 200 MWCO membrane?
Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Glucose will diffuse through the 200 MWCO membrane because its MW is 180. The MW of the protein albumin is much greater than 200 so it will not diffuse through the 200 MWCO membrane. 4.
