Fermentation Lab Report Introduction: Fermentation‚ a type of anaerobic respiration that breaks down glucose into ethanol and carbon dioxide without the use of oxygen‚ is extremely vital in food processing. Especially useful in the making of bread and wine is yeast‚ a single-celled fungus. The rate of fermentation of these products can be done by measuring the amount of carbon dioxide produced by the work of the yeast. The specific variable we tested was the volume of fructose in each vial solution

Investigating Factors That Affect Rates Of Reaction Aim: How does the mass of calcium carbonate affect its rate of reaction with hydrochloric acid? Hypothesis: I hypothesize that when the mass of the calcium carbonate increases‚ the rate of reaction of the calcium carbonate and hydrochloric will also increase. The collision theory states that the more successful collisions there are within the reaction‚ the faster the rate of reaction. When the mass increases‚ so does the number of particles

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

This lab was completed to determine the rate in which fermentation occurs in different sugars and to compare the rate of 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

Yeast Population Lab Report During this experiment we were trying to determine how food availability affects CO2 production (related to population growth). We investigated how one factor influences the change in yeast population growth as measured by the amount of carbon dioxide produced. The yeast that you buy in the store contains living organisms–invisible small one celled‚ microorganisms. As long as they are kept dry‚ they are inactive. When they are given food‚ moisture and warmth‚ they

Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air‚ but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Here is a molecular model of a glucose molecule. You do not need to memorise the diagram for you GCSE exam‚ but it should help you to understand that a molecule of glucose contains six atoms of Carbon (shown in blue)‚ twelve

oxygen released for the cold trial was 38 mL‚ 11 mL less than the control. Conclusion: The hot trial produced the most oxygen of all three trials. Heat tends to increase the rate of chemical reactions‚ explained in the article Temperature Effects (Introduction to Enzymes) by Chris Jamison. “Like most chemical reactions‚ the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree rise in temperature will increase the activity of most enzymes by 50 to 100% . Variations
