LS 1 LAB DEMO 1 13 January 2014 Introduction: The broader context of this lab was aimed at observing animals and documenting specific animal behavior patterns. Specifically‚ we were trying to determine if squirrels applied snakeskin randomly to certain areas of their body or if there was a specific technique to it in relation to escaping their predators. After an animal has determined that a predator is nearby‚ it must then take action to avoid encountering this threat. Encounters are most easily

of reactions that converts glucose to pyruvate with the concomitant formation of ATP. Three fates of this pyruvate produced exist. In this practical the production of pyruvate and acetaldehyde by fermentation of glucose is established. A series of test tubes was set up each containing glucose and yeast suspension in buffers at different pH values. These test tubes were incubated for an hour at 37℃. Trichloro-acetic acid solution was then added to the first 2 of the 4 test tubes prior to centrifugation

RaeAnne Smith HL Biology Y2 Soule: Period 7 10 October 2011 Affect of Sugars on Yeast Respiration Introduction Cellular respiration can be defined as the release of energy‚ or the breakdown of carbohydrates into carbon dioxide and water1. Cell respiration takes place in the mitochondria of animals and in the cytoplasm of plants. The formula for aerobic cellular respiration is: c6H12O6+ 6O2→6CO2+6H2O Aerobic respiration occurs when oxygen is present‚ while anaerobic respiration occurs when

Description This program will determine the usable area of a house. The rooms are rectangular in shape and maximum of four rooms are allowed to be calculated at once. It will use the area formula for a rectangle to find the usable area of each room and once the calculation are made for each room it will print out the total usable area of a house to the output screen. Analysis This program will calculate the usable area in square feet of a house with a maximum of four rooms that are rectangular

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

What is fermentation and why does it matter ? Fermentation is the process in which glucose is broken down in the absence of oxygen. Fermentation matters for many reasons. It’s important in muscles because it allows the muscles to keep getting energy from glucose even though oxygen can’t keep up with supplying. Fermentation also takes away the end products of glycolysis so that glycolysis can continue breaking down glucose and releasing energy. Fermentation is also important to the baking industry
