Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Mashrek International School Investigate the Factors that Affect the Rate of Respiration in Yeast. (Temperature) Fawzi El Ansari Biology HL Title: Investigate the Factors that Affect the Rate of Respiration in Yeast. (Temperature) Aim: The aim of this experiment is to investigate the effect of changing the temperature on the rate of respiration in yeast. This will be done by placing equal amounts of yeast in each beaker that contains the same pH solution. Each beaker will be mixed with glucose

For the lab study that we are going to conduct I choose Yeast as my organism. First off Yeast is a microscopic fungus consisting of single oval cells that reproduce by budding or fission (is the splitting of an atom)‚ and capable of converting sugar into alcohol and carbon dioxide. When making your own bread‚ you can buy yeast in the grocery store. The yeast contains little brown grains that will carry out cellular respiration and grow when put in water with sugar. In order to conduct the lab the specific

discovered that certain types of solutions were created by biological processes. As he investigated this phenomenon he was led to investigate the field of fermentation where he essentially discovered the aerobic and anaerobic bacteria responsible for fermentation. This discovery‚ that a biological agent was responsible for the fermentation (and also for the spoiling) of wine and beer‚ shook the scientific world as many at the time believed in spontaneous eruption. But

Fermentation Lab Introduction For bacteria and many single-celled protists fermentation is a common anaerobic pathway that the cells use to collect energy from carbohydrates to form ATP. The process for fermentation begins in the cytoplasm with a process called glycolysis‚ which converts one molecule of glucose into two molecules of pyruvate. When glycolysis is complete four ATP would be produced but the net yield would be two ATP taking into account the initial investment of two ATP

The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and

alcohol fermentation and lactic acid fermentation. In alcohol fermentation‚ pyruvate (product of glucose in glycolysis) is converted to 2 molecules of ethanol (C2H5OH) and 2 molecules of carbon dioxide (CO2) while in lactic acid fermentation‚ pyruvate is reduced directly into lactic acid (Campbell and Reece‚ 2008). A good example of organism which produces ethyl alcohol and carbon dioxide through the process of alcohol fermentation is yeast (Madur‚ 2009). As a unicellular fungus‚ yeast is also
