Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water‚ it is on the outside of the cell‚ the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals

Microbial spoilage There are three types of microorganisms that cause food spoilage -- yeasts‚ moulds and bacteria. Bacteria are round‚ rod or spiral shaped microorganisms. Bacteria may grow under a wide variety of conditions. There are many types of bacteria that cause spoilage. They can be divided into: spore-forming and non-spore-forming. Bacteria generally prefer low acid foods like vegetables and meat. In order to destroy bacteria spores in a relatively short period of time‚ low acid foods must

environmental factors of Obesity Obesity is one of the most common issues is America today. Over the years the amount of obese people in America has increased greatly. This problem is not only affecting adults‚ but children also. Many people have tried to determine if obesity is caused by environmental factors or natural factors. Obesity is strongly influenced by environmental factors such as poverty‚ housing condition‚ work situation‚ fast-food‚ and sedentary lifestyles. One reason for the

These can involve finances of a foreign country‚ customs‚ culture‚ and trends. McDonald’s has been a worldwide corporate success‚ and much of this success has been due to their marketing decisions. Here‚ we will find out what

Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the absorbency will decrease. The absorbency

P.3 Explain the difference between physical and environmental factors involved in the development. People working in construction are being told to minimise environmental impacts when carrying out there work. Many negative impacts can be reduced during the planning stage of a build. Any new build will have a negative impact on home owners and businesses. There will be increased traffic on roads and the towns will be fuller. Once the construction has been completed there may be longer term impacts

Abstract The catalysis of enzymes within our bodies is essential for human survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze

test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function‚ which means having the optimum ph and temperature to catalyze a
