Measuring the efficiency of various carbohydrate substrates in yeast fermentation. Cherrishe Brown October 3‚ 2007 Dieldrich Bermudez BSC 2010L Sect# 0560 Discussion As expected in the experiment Glucose‚ Fructose‚ and Sucrose were all utilized for fermentation. Based on the rate of evolution of CO2 the yeast was most efficiently able to utilize the substrate Glucose‚ followed by Sucrose and Fructose respectively. Given more time I believe that Sucrose would have surpassed glucose in total

Respiration-Fermentation in Yeast Aim: To study the different of solution affect the gas forms during fermentation in yeast. Procedure: Refer to Lab manual Result: Questions: 1. Yes. 2. Sucrose. 3. When no oxygen the ATP will be produce. 4. Brewery. 5. Aerobic glucose and aerobic glucose oxygen. 6. CO2 and aerobic water. 7. CO2 and aerobic ethanol. Conclusion: The purpose of this experiment is to determine sucrose gas form during fermentation with yeast is the most CO2. Sucrose

of Woodworking Workshop and Offices Introduction Earlier today‚ I carried out a Health and Safety inspection of the above areas of our premises. The purpose of the inspection was two fold. First of all‚ to satisfy the requirements of the practical aspect of the NEBOSH General Certificate‚ and secondly to ensure that health and safety control measures in the above areas remained in force‚ and that we were complying with our statutory duties. Summary The inspection revealed that health

ABSTRACT In order to determine the effect of the substrate on the rate of respiration of yeast‚ Durham test tube method was used in the first experiment. In this method two test tubes was obtain‚ where test tube one contains distilled H20 with the 7 ml substrate glucose while test tube two contains distilled H20 and with the cofactor in the form of Magnesium sulphate MgSO4. Both tubes has 7 ml 10% yeast suspension. The height of the area filled with gas was measured‚ after thirty minutes the test

G10 science By Freya Li Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes

Osmolarity TITTLE: practical of estimation of osmolarity in tissues by bathing samples in hypertonic and hypotonic solutions. INTRODUCTION: Osmolarity is the osmolar concentration of plasma and is proportional to the number of particles per liter of solutions shown as (mmol/l). It is derived from the measures Na+ and K+‚ urea and glucose concentrations. Since the volume of solution changes with the amount of solute added also it change in temperature and pressure‚ osmolarity we can say it’s

Sofia Dominguez 10-O 19/03/14 Effect of pH on germination of seeds: Design Practical Introduction: The term pH stands for Hydrogen Potential it is used to determine the acidity of a substance. The pH scale goes from 0 to 14. The values that are smaller than 7 indicate the range of acidity. Higher pH values are alkaline and a pH of 7 is neutral. Acidity is a function of the concentration of hydrogen ions (H+)‚ or protons. The strength of alkaline solutions is measured by the concentration of hydroxide
