sugars‚ either in the presence of oxygen (Aerobically) or without oxygen (Anaerobically). The purpose of this experiment was to perform a quantitative investigation of the differences between Anaerobic and Aerobic metabolism using pea seedlings and yeast organisms [1]. Aerobically‚ sugars such as glucose are transformed into pyruvate [2] and then into Acetyl CoA. This is then put through the citric acid cycle which is a series of reactions that oxidize acetyl units into carbon dioxide [2]. Following

Cellular Energetics: The Rate of Cellular Respiration and Photosynthesis over Time Among Various Variables By: Ethan Barnett Introduction Cellular Energetics is the broad term that encompasses both cellular respiration and photosynthesis and refers to how energy changes and reacts within cells. Cellular respiration is the process by which cells break down sugars (ATP) in order to produce energy for other chemical reactions. Cellular respiration takes place mainly in the mitochondria and the reactants

wire‚ the temperature of the wire will be increasing. Measure the temperature using the infrared thermometer. Record the ammeter reading as the temperature increases 10°C before disconnecting the wire from the circuit and measuring the wire resistance immediately using the ohm meter. 4. Repeat procedure 4 when the temperature of the wire increases every 10°C until the highest temperature is reached and the measurements are recorded. Conclusion The hypothesis that when the temperature of a wire

Sucrose that was extracted from sugarcane is a highly effective substrate that is used during yeast fermentation (Alexander N.Glazer). An enzyme that breaks down sugar is produced by the yeast . The enzyme is produced in the cytoplasm as well as in a secreted form. This enzyme is a catalyst for the

MIC Practical Report Kerry Haarhoff 18 April 2012 3150540 Introduction Bacteria and fungi are both micro-organisms‚ however‚ fungi are spore-producing organisms whereas bacteria are not and fungi can be multicellular and bacteria is only a unicellular organism. These 2 micro-organisms‚ along with many other things circulate in the air within our environment. These micro-organisms then settle and become more prevalent in different areas. An experiment was conducted to see where

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

Yeast and Sugar - The Chemistry must be right Jansen‚ C. Gymnasium Felisenum‚ The Netherlands 14-04-2010 Summary Yeast can metabolize sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. In this experiment yeast ferment sugars anaerobically. When yeast ferments the sugars anaerobically‚ however‚ CO2 production will cause a change in the weight of the sugar/yeast-solution. This raises a further question: What is the effect of different kinds of sugars
