Hypothesis: Increasing the water temperature, when mixed with yeast and sugar, will cause foam to rise to a greater height because heat causes expansion in the sugar and yeast combination. Procedure: Using 5 clear plastic bottles, fill each of them with yeast and sugar(30g of sugar, 20g of instant quick yeast) One cup (8oz) of water will be added to the bottles each at different temperatures measured in degrees Celsius; water could be 40-50-60-70-80 degrees C or whatever the person may choose at
Investigation 1: Respiration of Peas Introduction: There are 3 main methods through which we are able to monitor/ measure the rate of cell respiration. These 3 include; measuring the amount of glucose consumed, measuring the amount of oxygen consumed and measuring the amount of carbon dioxide consumed. In this investigation i will focus on an experiment with the experimental method of measuring the amount of oxygen consumed. When wanting to measure the amount of oxygen consumed we use a tool
been used for thousands of years to bring into being food and beverages, for example cheese, yoghurt, beer and wine. Yeast is a fungus whose enzymes supports the crash of glucose into ethanol and carbon dioxide anaerobically. The enzymes in the yeast break down sugar (glucose) into alcohol (ethanol) and carbon dioxide gas: Glucose ⎯Yeast ⎯ →⎯ Ethanol + Carbon dioxide C6H12O6 (aq) ⎯Yeast ⎯ →⎯ 2 C2H5OH (aq) + 2 CO2 (g) This reaction, takes place in the deficiency of oxygen, is called fermentation.Enzymes
include aerobic respiration, anaerobic respiration and fermentation. Aerobic respiration is the most common and the most efficient means of generating ATP. Aerobic respiration can be referred to as the breakdown of glucose molecules in the presence of oxygen and water to release energy in the form of ATP. The other products of this reaction include carbon dioxide and water. The overall equation for aerobic respiration is C6H12O6+6O2+ H2O→ 6CO2 +12H2O+ energy (ATP). During aerobic respiration, there are
Introduction: Leuconostoc mesenteroides: It is an epiphytic bacterium that is found in natural environment widely, it plays an important role in several food and industrial fermenting companies. Leuconostoc mesenteroides is facultative anaerobe which requires amino acids and complex growth factors. [1] Lactic acid bacteria (LAB) variety which includes Leuconostoc species are found on crop plants L. mesenteroides is the most abundant LAB species to be found on fruits and vegetables and responsible
Introduction Biomass energy, a form of energy from organic matter, accounts for about 15% of the Philippine’s energy mix. The Philippines, an agricultural country and an archipelago with growing urban centers, is rich in potential biomass resources. However, the Philippines is still dependent upon fossil fuels. While generating both fossil and biological fuels require processing of organic matter, fossil fuels release the carbon from deep underground that has not been actively released for millions
