Effect of lipid solubility on permeability of plasma membrane

: To study the effect of lipid solubility of molecules on permeability of plasma membrane of animal cell. Introduction : Diffusion: In general, diffusion process occur when there is a concentration gradient between two region .Molecules (other than water) will move by diffusion as long as there is a concentration gradient. A concentration gradient exists when a particular type of molecule (like food coloring dye molecules) is not spread out in an even concentration, but exists in a higher concentration at some point. Discussing about the movement across the plasma membrane of cell, diffusion is the simplest type of passive transport, whereby diffusion does not require the cell to use energy. Only small molecules can cross the cell membrane by simple…


Title: The effect of temperature on beetroot’s cells membrane Objective: To use beetroot to investigate the effect of temperature on cell membranes andrelate the effect observed to the membrane’s structure and properties Introduction: Beetroot Beetroot is one of many type of beets known as Beta Vulgaris.It can be used in cooking and drinking as it is one of the source of vitamins, minerals, nutrients and antioxidant as well including magnesium, potassium, sodium and vitamin C and betaine. Betaine in the cells serve as organic osmolytes which are synthesized or taken from the surroundings by the cells for protection against osmotic stress, drought and high temperature. It is also important for cardiovascular disease. The high amount of nitrate content in the…
