Comparing the Rate of Fermentation of Yeast in Solutions with Different Concentrations of Glucose Brandon Bosley BIO 121 11/19/2013 Introduction: In our lab this week we tried to see how different amounts of substrates affect our organism‚ yeast‚ in its fermentation process. Yeast (Saccharomyces cerevisiae) is an organism that is cultured for the cells themselves‚ as well as the end products that they produce during fermentation. Yeasts are commonly known for the ethanol fermentation due

This scientific report will be based on cellular respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best

cellular respiration in germinating and non-germinating soybeans. Fermentation breaks down sugars for a source of energy. Cellular respiration is the process used by cells to produce energy from nutrients. This process allows sugars and foods to be broke down in order to obtain energy from adenosine triphosphate (ATP). Cellular respiration is vital for survival of cells. Oxygen‚ which acts as the fuel is required for aerobic respiration. Oxygen helps breakdown food and turn into ATP. Anaerobic respiration

TOPIC 3.7 + 8.1: CELL RESPIRATION 3.7.1 Define cell respiration. Cell respiration is the controlled release of energy from organic compounds in cells to form ATP (adenosine triphosphates). 3.7.2 State that‚ in cell respiration‚ glucose in the cytoplasm is broken down by glycolysis into pyruvate‚ with a small yield of ATP. Glycolysis in cytoplasm: Glucose 2 pyruvates + small amount of ATP (does not use oxygen) 3.7.3 Explain that‚ during anaerobic cell respiration‚ pyruvate can be converted

DEFINITION ANAEROBIC POND Anaerobic ponds are deep treatment ponds that exclude oxygen and encourage the growth of bacteria‚ which break down the effluent. It is in the anaerobic pond that the effluent begins breaking down in the absence of oxygen "anaerobically". The anaerobic pond acts like an uncovered septic tank. Anaerobic bacteria break down the organic matter in the effluent‚ releasing methane and carbon dioxide. Sludge is deposited on the bottom and a crust forms on the surface as show in
