Principles of Cellular Respiration Ashley Flannigan November 5th‚ 2013 Professor Ryan BSC2010 Lab Fall 2013 2220 ABSTRACT Students in a Biology 1 lab class constructed an experiment on Cellular Respiration by investigating the effects of temperature on crickets’ metabolic rate. By following the following procedures out of the Lab Manual‚ the students were able to find an almost accurate representation of the crickets’ cellular respiration rate under various temperatures in order to

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

This lab was split up into two different experiments‚ using different variables in each. During the first section of the lab‚ we investigated the what the effect of light is on both photosynthesis and cellular respiration. Our hypothesis about this effect was that the cuvette representing ‘no light’‚ being covered in foil‚ would result in a yellow CO2 indicator fluid‚ meaning that there was a decrease in pH and a high level of CO2 was present. Additionally‚ we hypothesized that the cuvette that was

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

Extraction of Caffeine from Lipton® Tea Leaves Nathaniel Camangon*‚ Kaila Bumagat‚ Franz Mari Burgos‚ Remigio Callanta Department of Chemistry‚ College of Science‚ University of Santo Tomas‚ Manila‚ Philippines Abstract This experiment mainly focuses on the extraction of pure caffeine by multiple extraction from commercially acquired tea leaves and determining its purity by melting point determination. A 0.02% yield of pure caffeine was obtained from 10.4978g of tea leaves (4 tea bags).

The effect of increasing substrate concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory

of alkaloid caffeine from tea leaves Date Submitted: September 3‚ 2014 Abstract Caffeine is one of the main constituents of tea leaves. In this experiment‚ 0.0039 g of pure caffeine was isolated from tea leaves. This was done through solid-liquid extraction followed by multiple liquid-liquid extraction. Then crude material obtained was then purified by sublimation. The isolated caffeine was subjected to thin layer chromatography (TLC) together with a standard caffeine. The Rf value

Respiration of Sugars by Yeast 1. PROBLEM STATEMENT: What is the effect of the type of sugar on the amount of carbon dioxide released by Yeast during aerobic respiration? 2. HYPOTHESIS: If the type of sugar is changed‚ the amount of carbon dioxide created will then increase because sugar is needed to for respiration so occur. If Fructose is added to the Yeast it will then respire the most Co2 because fructose is the largest sugar‚ its like using a hundred dollar bill instead of single dollars
