Did you know?
WebVisking tubing (sometimes referred to as dialysis tubing) is a non-living partially permeable membrane made from cellulose Pores in this membrane are small enough to prevent the passage of large molecules (such as starch and sucrose) but allow smaller molecules (such as glucose) to pass through by diffusion This can be demonstrated by: WebThe dialysis tubing membrane is used to represent the membrane of the small intestine: It is an accurate model because both are partially permeable so smaller particles can pass …
