Can glucose pass through visking tubing

WebMay 29, 2024 · Since glucose is a large molecule, its diffusion across a membrane is difficult. Hence, it diffuses across membranes through facilitated diffusion, down the … WebAug 28, 2024 · It was concluded that the dialysis tubing doesn’t allow all kinds of substances to pass readily through the pores of its membrane. This means that it is selective in its permeability to substances. The dialysis tubing was permeable to glucose and iodine but not to starch.
