RaeAnne Smith HL Biology Y2 Soule: Period 7 10 October 2011 Affect of Sugars on Yeast Respiration Introduction Cellular respiration can be defined as the release of energy‚ or the breakdown of carbohydrates into carbon dioxide and water1. Cell respiration takes place in the mitochondria of animals and in the cytoplasm of plants. The formula for aerobic cellular respiration is: c6H12O6+ 6O2→6CO2+6H2O Aerobic respiration occurs when oxygen is present‚ while anaerobic respiration occurs when

In this lab my group and I tested to see how yeast would react to different substances. Yeast is a fungi that releases carbon dioxide which can be used in the process of bread making. During this lab we used sugar‚ warm water‚ cornstarch‚ yeast‚ a gas sensor‚ plastic cylinders‚ and a laptop. The process of this lab was to create cellular respiration‚ which is what cells do to break up sugars into a form that the cell can use as energy. When yeast and a certain substance were combined‚ this substance

Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

Yeast infections are an issue that numerous ladies around the globe experience the ill effects of every day. Whether they are pregnant‚ experiencing an immune system ailment‚ or simply rundown‚ it can be hard for ladies to dispose of the persistent contamination. It can be excruciating and even cause harm to your reproductive organs. The medications and prescriptions used to dispose of the issue can be viable‚ yet numerous individuals like to go the normal course. Disposing of the yeast contamination

hypotheses based on predictions questions. First‚ yeast will metabolize sugar and produce a gas. This is because yeast is a living organism and all living organisms like yeast must use energy (such as sugar) to obtain energy. Yeast will metabolize sugar and gives off carbon dioxide as a by-product. For the second hypothesis‚ we were expecting that yeast will produce a gas when sugar is available. For the third hypothesis‚ we did not expect yeast to produce a gas when no sugar or other food is available

produced in different temperature. If we have different temperature of yeast (0*‚ 22*‚37* and 100*). The yeast solution will have no activity or very little to measure at 0*. Temperature at 37* would show the most activation or CO2 production. The yeast solution at 100* will show no activity because that high of a temperature will cause denaturing to occur.

Vaginal yeast infection (Candida Vaginalis) Vaginal yeast infection is an infection of the vagina‚ most commonly due to the fungus Candida albicans. Causes Most women will have a vaginal yeast infection at some time. Candida albicans is a common type of fungus. It is often present in small amounts in the vagina‚ mouth‚ digestive tract‚ and on the skin. Usually it does not cause disease or symptoms. Candida and the many other germs or microorganisms that normally live in the vagina keep each other

sugars‚ either in the presence of oxygen (Aerobically) or without oxygen (Anaerobically). The purpose of this experiment was to perform a quantitative investigation of the differences between Anaerobic and Aerobic metabolism using pea seedlings and yeast organisms [1]. Aerobically‚ sugars such as glucose are transformed into pyruvate [2] and then into Acetyl CoA. This is then put through the citric acid cycle which is a series of reactions that oxidize acetyl units into carbon dioxide [2]. Following

How to cure nail yeast infection? Yeast infection in the nail bed or also with known as Onychomycosis‚ is one of the health problems that can happen to anyone. Symptoms onychomycosis is as inflammation‚ swelling‚ yellowing color and texture change in nails. Although sometimes painful‚ but if the infection has spread the pain caused even this condition is unavoidable. Onychomycosis itself is triggered by certain conditions‚ such as not normally the pH levels of the skin‚ immune system weakening
