Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials are kept horizontal until all of the flies fully recover from the anaesthetic. One possible error that may have occurred was that some of the adult flies may have accidentally been left in the vials

AP biology FRQ Courtney DeMane 1.22.13 block 7 A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino‚ carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure‚ there are 4 levels. The first one being the primary level. These are made

A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can

Sang Kim Enzyme Catalyst Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A‚ B‚ C‚ and D. In activity A‚ the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction‚ to study the characteristics of an enzyme mediated reaction‚ and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H 2O2 present

Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding

IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction
