Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

Enzyme Catalysis Lab Problem: Before the lab‚ one should understand: • The general functions and activities of enzymes; • The relationship between the structure and function of enzymes • The concept of initial reaction rates of enzymes; • How the concept of free energy relates to enzyme activity; • That change in temperature‚ pH‚ enzyme concentration‚ and substrate concentration can affect the initial reaction rates of enzyme-catalyzed reactions; and • Catalyst‚ catalysis‚ and catalase

reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with ink inside it‚ when you write‚ ink comes out‚ right? You can draw‚ you can write‚ then when you finish and get your pen off of the paper‚ the ink stops coming out. Enzymes are like that‚ they

Abstract: After reviewing the basics of enzymes and catalysis‚ we take a dive into the wonderful world of catalase. Beginning with establishing a base line of just how much hydrogen peroxide there is in 5.0mL of the reacted solution; to figuring out exactly how much actually reacted after 300 seconds of catalyzed reaction. Follow the experiment from the beginning steps right to the end as you see where the students went wrong‚ interpretation of the results‚ and great answers to work sheet

Introduction Background Theory The usual equation for measuring electric current flowing through a series is I = V/R. The current flowing in a series is affected by the voltage and the resistor that is also creating the series. Electric current is a flow of electric charge through a conductive medium. These charge is in a form of moving electrons in a wire. The SI unit for electric current is ampere (A) and can be measured by using a device called ammeter. Change in temperature can change

A. Plan of the investigation The focus of the study is on the event of the Tiananmen Square Massacre and how the Chinese Communist Party government shocked the world. Moreover‚ the study focuses on the aftermaths and the international effects like how the United States decided how to deal with this violent act or how this event possibly encouraged protestors to fight against their corrupt government. This research paper will evaluate the extent of how international countries were affected
