Laboratory for Simple Diffusion Essay Example

The text presents experiments and observations on simple diffusion, dialysis, and facilitated diffusion. It provides the molecular weights of Na+ and Cl- and their ability to pass through membranes with different MWCOs. Certain MWCOs allow for diffusion from the left beaker to the right beaker, while smaller materials do not diffuse. Urea concentration is equally distributed between two beakers due to urea diffusion. The equilibrium time for facilitated diffusion is affected by glucose concentration and the number of carriers in membranes. The transport mechanism for Na+/Cl- involves simple diffusion influenced by actively transported glucose rather than salt. Glucose receptors exclusively bind to glucose. Additionally, it raises a question about whether equal amounts of glucose in both beakers would result in observable diffusion, suggesting that the absence of observable diffusion does not indic
