challenging to determine the figures in the cheek smear‚ but the bacteria form in the yeast wet mount were easily recognized. The direct staining was the following technique used. The cells were very easy to assess‚ well demarcated and had a very distinctive color. Instead of the background and around the cell in the cheek smear‚ the indirect staining way seemed to in fact tint the cells. Identification of the yeast cells by the indirect system was done effortlessly while the cells in the plaque

Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of an enzyme is to increase the rate of a reaction;

this lab is to test the effects of different variables mixed with the reaction of hydrogen peroxide and yeast‚ yeast being the catalase. The variables that will be changed are temperature‚ pH‚ and concentration. Our class began a lab based around enzymes and how they react when different variables are changed‚ such as temperature‚ pH‚ and concentration of the yeast or hydrogen peroxide. The yeast acted as the enzyme‚ which produces catalase needed for our desired reaction with the hydrogen peroxide

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration

Latin (Ferver which means to ‘boil’).As during fermentation there is lot of frothing of the liquid due to the evolution of carbon dioxide‚ it gives the appearance as if it is boiling. Sugars like glucose and sucrose when fermented in the presence of yeast cells are converted to ethyl alcohol. During fermentation of starch‚ starch is first hydrolysed to maltose by the action of enzyme diastase. The enzyme diastase is obtained from germinated barley seeds. Fermentation is carried out at a temperature

of baker’s yeast (Moyad‚ 2008). The connection between Baker’s yeast and UV radiation is the effect it has on the immune system‚ which should have a counter interaction due to the fact that Baker’s yeast enhances the immune system while UV radiation negatively affects the immune system (Moyad‚ 2008). Bakers yeast is also has a rapid cell division and can easily be tested in laboratory settings. Since they follow basic growth standards for experimentation this makes for a great yeast cell to use(Duina

We had taken a water bottle and filled it with water and sugar‚ then we put yeast in it and got as much air out as possible to give it the no air factor‚ at that point we attached a balloon and watched it get sucked into the bottle. Our results were that at 15 minutes Earth had a circumference of 18.5 cm and 0 cm for the Moon. At
