FERMENTATION INTRODUCTION The aim of this experiment was to study the process of alcoholic fermentation in Saccharomyces cerevisiae (yeast cells) and measure the rate of Co2 production during anaerobic breakdown of the respiratory substrate‚ sucrose‚ in the yeast cells. The effects of an inhibitor on respiratory enzyme were also looked at. It is hypothesized that the five different reaction mixtures shown in Appendix 1 with their contents‚ would each have a CO2 production that is not the same

the filtration rate both decreased. 5. When the radius of the afferent arteriole was increased‚ the pressure and the filtration rate both increased. 6. When the radius of the efferent arteriole was decreased‚ the pressure and the filtration rate both increased. 7. When the radius of the efferent arteriole was increased‚ the pressure and the filtration rate both decreased. Activity 2: 1. When you increase the blood pressure‚ the glomerular capillary pressure and the glomerular filtration rate

Flow Tube Radius on Glomerular filtration. Data/Results: Questions: Please answer the questions in complete sentences and explain your answers. 1. What effect does increasing the afferent radius have on glomerular filtration rate and pressure? Both the rate and the pressure increase as you increase the afferent radius. 2. What effect will decreasing the efferent radius have on glomerular filtration rate? When I decreased the efferent radius‚ it increased the filtration rate. Please see table below:

bacteria is a fermenter they will use the sugars to make ATP. If the bacteria is a fermenter of lactose/sucrose the EMB plate we used will “clearly differentiate between the colonies of lactose fermenting and non-fermenting microbes. In the same medium sucrose was also included to differentiate between coliforms that were able to ferment sucrose more rapidly than those that were unable to ferment sucrose” (Cheeptham & Lal‚ 2007). If it is catalase positive it will produce bubbles with the drops of hydrogen

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

7–9) 9. Smaller MWCO numbers translate to smaller pore sizes‚ which correlate with lower filtration rate. Powdered charcoal did not appear in the filtrate using any membrane. Increasing the force driving filtration increases filtration rate. Increasing the pressure gradient effectively increases the filtration rate. By examining the filtration results‚ we can predict that the molecular weight of glucose must be greater than NaCl but less than powdered charcoal
