FROM YEAST AND EFFECT OF pH ON ENZYMATIC ACTIVITY Jenelle C. Faustino‚ John Gambit B. Garcia‚ Fatima S. Jusay‚ Oliver Alexander B. Lao and Eunice L. Licudine Group 4 2 E Medical Technology Biochemistry Laboratory ABSTRACT Enzymes are substances that are produced by living organisms and act as catalysts in order to speed up or chance a chemical reaction without changing itself at the end of the reaction. Invertase was extracted first from baker’s yeast. Determination of the effects of

Lab 04: Sugar Respiration in Yeast Sugars are vital to all living organisms. The eukaryotic fungi‚ yeast‚ have the ability to use some‚ but not all sugars as a food source by metabolizing sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. The decomposition reaction that takes place when yeast breaks down the hydrocarbon molecules is called cell respiration. As the aerobic respiration breaks down glucose to form viable ATP‚ oxygen gas is consumed and carbon

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚

Title: Inhibition of Yeast Glycolysis Abstract: The purpose of this experiment was to study carbon dioxide emissions from yeast‚ as well as their respiratory rate and to use that data to study how glycolysis inhibitors affect the respiratory rate. In our experiment‚ we tested how 8.75% glucose + 1.25% NaCl‚ 8.75% glucose + 1.25% glucose-6-phosphate‚ 8.75% glucose + 1.25% citric acid‚ and yeast solution‚ all mixed with distilled water‚ affect carbon dioxide volumes and respiratory rate. Our results

* Would yeast produce more carbon dioxide with the presence of sugar at room temperature or in an incubator? | -Observing Cellular respiration in yeast cells. | Yeast Lab Background Information: Yeast is a tiny unicellular fungus that obtains energy from outside sources (a heterotroph) mostly sugars in order to grow and reproduce. Yeast is often used in bread dough to make the dough rise. With the presence of oxygen a yeast cell creates energy by performing cellular respiration and
