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

The plasma or cell membrane exhibits ability for the cell to discriminate in its chemical exchanges with its environment and this makes cell membrane fundamental to life. This property can only be possible because of the cell membrane’s selective permeability (Campbell and Reece‚ 2002). The structure of the membrane can be best illustrated by the fluid mosaic model where the membrane is said to be a fluid structure with various proteins embedded in or attached to a bilayer of phospholipids (Campbell

CHEMISTRY COURSE TITLE: General Organic Chemistry COURSE CODE: CHM 121 ‚ UNIT: 2.0 . INTRODUCTORY AND IMPORTANCE OF ORGANIC CHEMISTRY Organic chemistry is the study of the compounds of carbon. Carbon compounds are far more numerous than those of other elements because carbon are able to bond together to form a wide range of chains and rings. The subject is named organic chemistry because living organisms are composed of carbon compounds. Organic chemistry could be regarded as the

Investigating the effects of temperature on cell membranes Independent variable: Temperature of beetroot Dependent variable: Absorbency of light Hypothesis: As temperature rises to its optimum temperature‚ the absorbency of light will increase because protein is an enzyme and will therefore be affected by temperature. This is because more beetroot dye will pass through the cell membrane and then into the distilled water. The deeper the colour of the beetroot dye‚ the higher the absorbency

increase the permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim of this practical is to use beetroot to examine the effect of temperature on cell membranes and relate

Organic vs. non organic There is a vast majority of food in our world today‚ when we consume this food we must stop to think about what exactly it is made of. In today’s society we are always looking for the best healthy foods that are available to us. We want good‚ nutritious‚ healthy foods so that we can live a long and healthy life. We live in a world where we have fast‚ cheap and processed foods all around us. Have you ever considered going a different route? Organic is a different way to eat

MCOPS‚ Manipal ANALYTICAL METHODS FOR RESIDUAL SOLVENTS INTRODUCTION: Organic solvents are routinely applied during synthesis of drug substances‚ excipients‚ or during drug product formulation. They are not desirable in the final product‚ mainly because of their toxicity‚ their influence on the quality of crystals of the drug substance and their odor or taste‚ which can be unpleasant for patients. To remove them‚ various manufacturing processes or techniques (usually under
