AP Sample 4 Lab 2 - Enzyme Catalysis - BIOLOGY JUNCTION
This lab will observe the conversion of hydrogen peroxide to water and oxygen gas by the enzyme catalysis. The amount of oxygen generated will be measured and used to calculate the rate of the enzyme-catalized reaction. Enzymes are proteins produced by living cells.
INTRODUCTION: The enzyme used in lab 2A and 2B – catalase – has four polypeptide chains, each composed of more than 500 amino acids. This enzyme is found throughout aerobic
Experimental Lab: Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston, 2007). A catalyst is any substance that increases the rate of a chemical reaction (by lowering the activation energy of the reaction) (Denniston, 2007). In this experiment we are using Hydrogen peroxide (the substrate for this experiment) is.

ENZYME CATALYSIS
In an enzyme-catalyzed reaction, the substance to be acted upon, the substrate (S), binds reversibly to the active site of the enzyme (E). One result of this temporary union is a reduction in the energy required to activate the reaction of the substrate molecule so that the products (P) of the reaction are formed. In summary:

Enzyme Catalysis
• observe the role of an enzyme (catalase) in the conversion of hydrogen peroxide (H 2O 2) to water and oxygen • determine the rate of the enzyme-catalyzed reaction Before beginning this laboratory, students should understand • the general functions and activities of enzymes • the relationship between the structure and function of enzymes
AP Biology Lab 2: Enzyme Catalysis - berwicksclasses.org
AP Biology Lab 2: Enzyme Catalysis. Background: Enzymes are the catalysts of biological systems. They speed up chemical reactions in biological systems by lowering the activation energy, the energy needed for molecules to begin reacting with each other. Enzymes do this by forming an enzyme-substrate complex that reduces energy required for the ...

AP Biology Lab 2 Enzyme Catalysis Introduction Enzymes catalyze reactions by lowering the activation energy necessary for a reaction to occur. In this laboratory, you will study some of the basic principles of molecuar movement in solution and perform a series of activities to investigate these processes.
four pre-lab questions. The method our group chose to conduct this lab was to set up four different substrate-catalyst combinations while attempting to determine if there was a direct correlation between catalyst-susbtrate ratio and reaction rate. We did this by performing two trials of each, during which observations and data were collected ...
