from areas of high concentration to low concentration‚ thus requiring no energy. Many of the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose

Cell Osmotic Fragility‚ Solute Permeability and Diffusion Potentials of Permeable Membranes Introduction This experiment examines cell membrane permeability‚ osmosis and membrane voltages; all of which are important in understanding how cells are affected by their environment. The movement of water across membranes is important for cell volume and thus the volume of extracellular compartments. The mechanisms for solute transport are essential in maintaining cell functions and homeostasis. Furthermore

There was a controlled and an experimental substance. The controlled substance was the one with starch in the dialysis bag‚ and the experimental substance was the one with starch and amylase in the dialysis bag. Both had the same solvent outside of the bag (Lugols and Distilled Water). The color change differed from inside and outside the bag as time went on‚ and at the end of the 45 minutes‚ the two bags had changed colors. The solute in the controlled substance had a darker color to it‚ with it

The fumarase activity was determined by the highest absorbances using the Cary50 set at 250nm. The pre-dialysis elution pool was pooled together from fractions 17-18 and the flow-through pool was determined to be fractions 2-9.
