the tube with the highest concentration of yeast will produce the most carbon dioxide and will have the fastest rate of alcoholic fermentation. Results Two separate experiments were conducted to determine the effect of yeast concentration and pH level on the rate of fermentation. The first experiment involved the placement of different concentrations of yeast‚ glucose‚ and distilled water in four different tubes. Pipette pumps were placed on each tube to allow the solution to ferment

Analysis EXECUTIVE SUMMARY: Analysis of drilling fluids is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and to test for contaminates such as NaCl

Krupa Desai Cell Biology April 3‚ 2013 Lab: Biosynthesis of Starch Introduction: In this lab we learned the concept and procedure of synthesizing starch. We also learned the effects of pH and temperature on the reaction rates of amylase.. In the process of the synthesis lab we learned phosphorylation using a potato‚ which was what we synthesized. The phosphorylation took place after the addition of primer. There are two different types of starches used are amylose and amylopectin. To test

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

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‚

Enzymes do not get used up during the reaction and can keep catalyzing reactions till there are no more substrates. However enzymes are tertiary proteins structures and are very dependent on the environment in which they reside in. Many factors such as pH‚ temperature‚ and salinity can affect the shape of the active site on the enzyme and decrease the rate of the reaction. Many tertiary proteins such as enzymes depend on various weak ionic bond‚ hydrogen bonds‚ disulfide bridges‚ and hydrophobic interactions(van

Enzyme Activity Lab Objective: To determine the effect of temperature‚ PH and enzyme concentration on catalase activity. Introduction: What is an enzyme and how the enzyme works. Any of a group of complex proteins or conjugated proteins thatare produced by living cells and act as catalysts in specific biochemical reactions. The system in which enzymes work is often referred to as the ’lock and key’ system it’s where the enzyme and the substrate lock together. The substrate then unlocks into
