TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost all of the chemical reactions in living organisms. Without enzymes‚ these

Processes Lab Section 903 Tianna Clarke Materials and Methods Part I – Restriction Enzyme Digestion To begin this experiment‚ the DNA molecules must be cut into smaller fragments with distinct enzymes called Restriction Enzymes through a process called Restriction Enzyme Digestion. Four microtest tubes were labeled 1 through 4 and added 10 µl of Enzyme Reaction Buffer to each of the four reaction tubes using a micropipette. DNA‚ and Enzyme 1 and 2‚ were then added to the reaction tubes using a new

Unfortunately‚ we did not have any data for week four due to the Astros parade‚ and during the fifth week of data collecting‚ two nightcrawlers went missing during the experiment in one of the containers‚ so the results for the Gain at 0.06% were inaccurate and the six week mass count as shown in figure one‚

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

Introduction In order to identify new materials‚ scientists use a variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method‚ which was proposed by John Dumas in 1826‚ makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta

Abstract The Tuskegee syphilis experiment was an infamous clinical study conducted between 1932-1972 in Macon Country‚ Alabama by the U.S Public Health Service. The purpose was to study the natural progression of untreated syphilis in rural African American men who thought they were receiving free health care from the U.S government; about four hundred African American men were denied. The doctors that were involved in this study had a shifted mindset; they were called “racist monsters”; “for

Lab 4: Methods of limits Elizabeth Bryan Florida State University Lab 4: Method of limits. Sound waves are created when an object vibrates. They have two main components: frequency (pitch; measured in Hertz (Hz)) and amplitude (loudness‚ intensity; measured in decibels (dB)). The method of limits is a psychophysical method in which a particular dimension of a stimulus‚ or the difference between two stimuli‚ is varied incrementally until the participant responds differently. The change in stimulus
