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

The Effect of Temperature on Beet Root Membranes What is the affect of temperature on beetroot membranes? Hypothesis: It is hypothesized that as the temperature increases‚ the deeper red the beetroot water will be. At higher temperatures the proteins in the beetroot plasma membrane will denature‚ leaving holes in the membrane and allowing the red pigment in the cell sap to seep out into the water around it. Variables: Dependent-The dependent variable is the absorbency of the beetroot water

UTILIZATION OF BANANA PEEL WASTE TO PRODUCE ETHANOL I Introduction Due to increasing demand for energy‚ renewable energy sources particularly waste products like banana peel waste can be utilized to produce ethanol‚ as the vitality of ethanol are well known in science world‚ besides the methods of producing it is incomplex and it can give big impact to the world. II Body A Ethanol is widely recognized these days as a very promising alternative source of energy (Low & Isserman

Ethanol Production Ethanol is the type of alcohol found in alcoholic drinks such as wine and beer. Its chemical formula is: C2H5OH. Glucose from plant material is converted into ethanol and carbon dioxide by fermentation. The enzymes found in yeast (single-celled fungi) are the natural catalysts that can make this process happen. Here is the word equation: Sugar → Ethanol + Carbon Dioxide

Mayra Guadalupe October 29‚ 2012 The effect of temperature on beet cell membranes Introduction: Cell membrane is the plasma like substance that separates different organelles and molecules within an organism. The cell membranes vital function is to permit passage of protein and enzymes through their wall. Red beets‚ also known as Beta Vulgaris has a red pigment that is located in its large central vacuoles. It is my hypothesis that if the cell membrane is to experience extreme temperatures

Introduction Ethanol most commonly which is produced through the fermentation of glucose by yeast cells. Fermentation is an energy-yielding process that cells carry out in the absence of oxygen. Although fermentation does not provide much usable energy for the cell‚ it is sufficient for yeast cells. Yeast cells produce ethanol and CO 2 as byproducts‚ and the ethanol produced valuable energy source. There is much interest in ethanol as an energy alternative which are nonrenewable and contribute significantly

After reading Ethanol Madness in The Economics of Public Issues (Miller‚ Benjamin‚ & North)‚ most of America is not benefiting from the production of ethanol. The only ones benefiting from ethanol requirements are ethanol producers‚ farmers‚ Brazilian farmers and politicians. Congress and the United Sates government are both benefiting from the ethanol requirements and the import tariff on ethanol. In the chapter I learned that ethanol is not as renewable as it seems. It is an alternative to biofuel

Ethanol‚ a Fuel? Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch‚ the ground grain is then mixed with water‚ heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the

Ethanol fuel is ethanol (ethyl alcohol). Ethanol‚ also called ethyl alcohol‚ pure alcohol‚ grain alcohol‚ or drinking alcohol‚ is a volatile‚ flammable‚ colorless liquid. A psychoactive drug and one of the oldestrecreational drugs known‚ ethyl alcohol produces a state known as alcohol intoxication when consumed. Best known as the type of alcohol found in alcoholic beverages‚ it is also used in thermometers‚ as a solvent‚ and as a fuel. In common usage‚ it is often referred to simply as alcohol or spirits
