Factors that increase permeability

a. t oil/water partition coefficient of the solute increases solubility in the lipid of the membrane.

b. i radius (size) of the solute increases the speed of diffusion.

c. i membrane thickness decreases the diffusion distance.

- Small hydrophobic solutes have the highest permeabilities in lipid membranes.

- Hydrophilic solutes must cross cell membranes through water-filled channels, or pores. If the solute is an ion (is charged), then its flux will depend on both the concentration difference and the potential difference across the membrane.

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
