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

understand the process of fermentation of yeast in different concentrations of sucrose. The experiment worked with yeast and sugar (sucrose and glucose) to determine the rate of fermentation by testing the pressure of C02 in the test tube. The experiment tested the metabolic capability of yeast anaerobically meaning no oxygen was present (this was ensured by the thin layer of oil on the top of the solution). This means that the metabolic rate of the yeast could be determined by testing the pressure

high and low temperatures; low amounts of oxygen and water; and high levels of salinity‚ acidity‚ alkalinity‚ and radiation. Examples of extreme environments on Earth are hot geysers and oceanic thermal vents‚ Antarctic sea ice‚ and oxygen-depleted rivers and lakes. Organisms that have evolved special adaptations that permit them to live in extreme conditions are called "extremophiles."

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

Effects of Molasses Concentration on Yeast Fermentation The purpose of this lab was to determine how yeast cells are affected by the concentration of a food source‚ and for our purposes‚ the food sources were corn syrup and molasses. Our hypothesis was that the yeast cells would ferment the most when there was a higher concentration of molasses/corn syrup. In order to test this‚ we created 10 test tubes with decreasing concentrations of molasses/corn syrup using a serial dilution. Each test

Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

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

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
