Being lactose intolerant means that people cannot digest lactose products properly. This condition effects people at all different levels. The symptoms being shown with this are bloating‚ diarrhea‚ gas‚ and nausea. This condition is due to the large intestine not being able to break down the lactose into glucose‚ because of the lack of enzyme lactase. In order for the large intestine to work properly it needs certain dairy products such as yogurt to help with digestion. When a person id lactose intolerant

carcinogen using yeast as a model. Aging is indeed a potent carcinogen. Somatic mutation theory states that cancer is a genetic disease.It is so because cancer cells proliferate at a rapid pace as a result of mutations in their genes they have accumulated in themselves over the course of their lifetime. Hence the key points are Aging and Genetic instabilities that follows with it. I want to study yeast cells as a model as they are largely analogous to stem cells in humans. Many mammalian cell cycle genes

Respiration Objectives 1. 2. 3. 4. 5. 6. To describe oxidation and reduction in terms of electron and H+ transfer. To distinguish anaerobic from aerobic cellular respiration in terms of ATP‚ oxygen‚ and chemiosmosis. To demonstrate that carbon dioxide is a product of cell respiration. To determine the effect of boiling on the aerobic respiration of bean seeds and explain the result in terms of enzyme activity. To measure the rate of oxygen consumption in germinating bean seeds. To determine the

Carbohydrate Metabolism Carbohydrate metabolism starts with digestion in the small intestines. This is the site where monosaccharides are absorbed into the blood stream. This type of metabolism is basically considered to be glucose metabolism because carbohydrates are eventually broken down into glucose so that it can diffuse into the blood stream. There are three hormones in the body that control the concentration on glucose in the body: Insulin‚ glucagon‚ and epinephrine. If sugars are too

METHODOLOGY After formulating the hypothesis that the molecular weight affects the rate of diffusion‚ three different kinds of substances --potassium permanganate (KMNO4)‚ potassium dichromate (K2Cr2O7) and methylene blue (C16H18N3SCl)‚ were used to test the validity of the hypothesis. Potassium permanganate is an inorganic chemical compound which is in violet liquid form; potassium dichromate is an orange inorganic chemical reagent and methylene blue is a chemical compound commonly used for staining

to convert carbon dioxide and water into simple sugar called glucose‚ which provides a basic energy source for the plant. Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. Chloroplasts contain molecules of a green pigment called chlorophyll‚ consisting largely of carbon and hydrogen. It gives green color and absorbs the necessary light for photosynthesis. Chloroplasts are found in palisade cells‚ they have a large surface area‚ which means there is more change

An experiment to demonstrate the effect of temperature on fermentation by yeast The purpose of this laboratory is to observe how temperature affects the metabolism of Grape juice by visibly noting the volume changes of identical food mixes containing yeast at different temperatures. Background Information If yeast is added to a liquid containing sugar and other nutrients‚ kept at an appropriate temperature (and deprived of oxygen)‚ it will turn the sugars into ethanol (alcohol) and carbon

Which Flour Has The Greatest Amount of Gluten Eliza Kate Introduction My problem is to find which flour has the most gluten. My problem is important to me because I like to bake. The problem is important to the world because some bakers may need to use a certain type of flour for the foods they make and I would like to help them out as if I were a professional. My independent variable is the type of flour and my dependent variable is the amount of gluten. Research Flour‚ Wheat‚ Cereal

Making Bread with Yeast By Rebecca Coles Introduction Bread is such a common food‚ who would expect it to be made in such a fascinating and clever way? A simple loaf contains just four main ingredients; flour (the main ingredient)‚ warm water (the yeast prefer the water warm)‚ salt and of course the yeast‚ tiny microscopic fungi that help the bread rise. Although fascinating the process is surprisingly simple; first‚ the flour‚ sugar and water is mixed together with yeast to make the bread

Reaction Rates of Barley Alpha Amylase with Starch at Specific pH ’s and Temperatures Page 1 Abstract Enzyme ’s are used as catalysts in certain reactions. They help lower the activation energy needed for the reaction to go to completion. At optimum temperature and pH the amount of collisions of substrate and enzyme is at its highest‚ any deviation from the optimum temperature and pH will result in the denaturization of the enzyme. The purpose of this experiment is to find the optimum
