    by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate

    Title Membrane Permeability Aim To determine the effect of various chemicals and high temperature on the membrane permeability of beetroot Hypothesis Organic solvent and high temperature will destroy the cell membrane and make it permeable to the red pigment. The higher the concentration of the alcohol‚ the greater will be this effect. Principle Beetroot is the material used in this experiment to demonstrate the effects of high temperature and chemicals on the permeability of the cell membranes

    The Cell membrane surrounds all living cells and is the most important organelle‚ there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The membrane controls how and what substances can move in and out of the cell/organelle The structure of the membrane is often referred to as the “Fluid Mosaic Model”; this is because of the way it is structured It is composed of phospholipids‚ proteins‚ and carbohydrates‚ which are arranged in a fluid

    Part 1 Part 1 of the experiment investigated the effect of different temperatures on beetroot cell membranes (a type of plant cell). Through this experiment‚ the process of diffusion and osmosis was in action. Various temperatures ranging from low temperatures to high temperatures such as -5⁰C‚ 5⁰C‚ 30⁰C‚ 50⁰C and 80⁰C were used to investigate the temperature effects on beetroot cell membranes. The hypothesis predicted that the higher the temperature the darker the beetroot substance and the lower

    Membrane Processing MEMBRANEFILTRATION A membrane or‚ more properly‚ a semipermeable membrane‚ is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Membrane filtration enables to separate particles with a diameter smaller than the pore diameter in the membrane from the liquid feed‚ by applying a driving force (pressure) over the membrane. The membrane technology consists principally of Microfiltration (MF)‚ Ultrafiltration

Your last paragraph was very detailed with great information about the cell membrane‚ you stated “ The cell membrane is very thin and fragile‚ and it contains two different types of proteins. “Integral proteins are part of the membrane structure and cannot be removed without damaging or destroying the membrane. Peripheral proteins are bound to the inner or outer surface of the membrane and are easily
