Anaerobic Respiration Lab Aim: To identify the products of anaerobic respiration in yeast Apparatus and Materials: boiling tubes‚ delivery tube‚ bungs‚ sugar‚ yeast‚ lime water‚ liquid paraffin‚ Bunsen burner Procedure: Water was first boiled in the boiling tube. A small amount of sugar was then dissolved into the boiled water‚ which was allowed to cool. A little bit of yeast was added then stirred. Apparatus was set up as shown in Figure 4. A layer of liquid paraffin was added to the surface

Respiration and Fermentation Lab on-line #10 Objectives: Monitor respiration activity in yeast by observing CO2 production as sugar is metabolized Investigate the effects of temperature on yeast fermentation Respiration Living cells use ATP (adenosine triphosphate) as their energy "currency". The energy released when a molecule of ATP is hydrolyzed (ATP ADP + PO4) is used to drive cellular reactions. To stay alive‚ a cell must continually regenerate its supply of ATP (from ADP

experiment to investigate the amount of respiration by how much carbon dioxide is produced and how using different sugar types affects rate of respiration. The experiment showed that the yeast produces the highest volume of CO2 with glucose. It also showed the yeast respires at its lowest rate with sorbose and maltose was in between the rate of yeast respiration of glucose and maltose. Introduction In this investigation we are going to investigate the amount of respiration by how much carbon dioxide is produced

ABSTRACT The hypothesis which states that the simpler the nature of substrate‚ the faster the rate of cellular respiration of yeast was tested using the smith fermentation tube method. The experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the

Cellular Respiration in Yeast Lab Report Form Your Name: Katlin Moore “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts? * Yeast

Experiment 5 : Cellular Respiration Experiment 6 : Photosynthesis Title: Cellular Respiration Objective: To observe and determine cellular respiration in yeast/onion cells. * Measure respiration rate using different substrates. * Measure respiration rate at different temperature. Introduction: In this laboratory experiment‚ we are given 3 task. The first one is respiration in yeast. Second is respiratory indicator and the third one is observing mitochondria in yeast/onion cell. The

used to guage the rate of respiration by measuring the time taken for it to turn colourless. Methylene blue‚ acting as a hydrogen acceptor‚ is decolourized during the respiration of yeast. By measuring the time taken for a fixed amount of the dye to be decolourized‚ the relative rate of respiration (a catabolic process) can be deduced. Results: The yeast mixture in test tube A turned blue at first but slowly changed back to its original colour and stayed that way. The yeast mixture in test tube B

of Energy Production During Yeast Fermentation Sarah Sulon Biology Lab 111L Dr. Murray October 25 2010 Abstract The experiment was conducted to determine the impact different sugar types have on yeast fermentation. It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast with solution of no sugar‚ glucose

Experiment 14. Dehydrogenase in yeast During respiration‚ hydrogen atoms are removed from glucose molecules by enzymes called dehydrogenases and passed to various chemicals called hydrogen acceptors. As the hydrogen atoms pass from one hydrogen acceptor to another‚ energy is made available for chemical reactions in the cell. In this way‚ substances such as glucose provide energy for vital reactions in living organisms. In this experiment‚ a dye called methylene blue acts as an artificial hydrogen
