tubing made of selectively permeable membrane
The dialysis machine is time - consuming while the properly funtioning nephron can get work done quickly
The dialysis tubing is meant to represent the semi permeable membrane of a cell. Like the cell membrane, dialysis tubing has holes or pores that only allow certain things to pass through. A cell membrane similarly will only allow certain things to pass in and out.
Dialysis tubing is often used to emulate the selective permeability of the cell membrane.
Yes, oxygen molecules are small enough to pass through the pores of dialysis tubing. This allows oxygen to diffuse into the dialysis tubing from a surrounding solution or environment.
Yes, protein can diffuse through dialysis tubing due to its small size and ability to pass through the pores of the tubing.
No.Hydrogen ion cannot pass through the pores of dialysis tubing.
molecular weight higher than the pore size of the tubing or dialysis bag material doesnt go.
A dialysis tubing pore is usually 20nm, but some dialysis tubings are specially made to have smaller or larger pores ranging from .85 nanometers to 30 nanometers.
I don't know unless you give more details!
Urea passes through the dialysis tubing into the dialysis fluid due to the process of diffusion, where molecules move from an area of higher concentration to an area of lower concentration. The dialysis tubing is semi-permeable, allowing small molecules like urea to cross while retaining larger molecules and cells. As urea accumulates in the blood and reaches a higher concentration than in the dialysis fluid, it diffuses out to achieve equilibrium. This process helps remove waste products from the blood in dialysis treatments.
Yes, phenolphthalein can pass through dialysis tubing, as it is a small organic molecule. Dialysis tubing is designed to allow the passage of small solutes while retaining larger molecules, so substances like phenolphthalein, which has a molecular weight of about 318 g/mol, can diffuse through the pores of the tubing. This property is often utilized in experiments to demonstrate diffusion and the selective permeability of membranes.
