    Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

The morphological changes associated with early phase DN comprise diffuse thickening of the glomerular capillary basement membrane together with the nodular glomerulosclerosis (2). Although the pathophysiology of DN is mainly occur due to hyperglycemia‚ it is believed to involve a combination of genetic and environmental factors. Crucially‚ DN is

    require the use of ATP energy. During passive processes‚ molecules are transported through the membrane by differences in concentration or pressure between the inside and outside of the cell. Two important types of passive process are diffusion and filtration. Every cell in the human body uses diffusion as an important transport process through its selectively permeable membrane. During diffusion‚ molecules that are small enough to pass through a membrane’s pores or molecules that can dissolve in the

    * A reactant in an enzyme-catalyzed reaction is called a substrate. The area of the enzyme that binds to the substrate is called the active site - where the action takes place. * Cofactors and coenzymes are small molecules or ions that help enzymes to act.
