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

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

Enzymes are naturally occurring biological catalysts that are extremely efficient and specific. Enzymes accelerate the rate of a reaction by factors of at least a million as compared to the same reaction without the enzyme. Most biological reaction rates are not perceivable in the absence of the enzyme. The term enzyme was first used by a German pshysiologist Wilhelm Kühne in 1897. There are over 700 different kinds of enzymes that have been identified. Enzymes can be classified into several categories

We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: 2 H202 (aq) 4 2 H20 (l) + 02 (g) We can trap the

Enzyme Catalysis Introduction: Enzymes are produced by living organisms as proteins. These enzymes perform as catalysts to bring about a chemical reaction. In fact‚ most reactions are catalyzed by enzymes during reactions in the cell or in the human body. A catalyst that enzymes pose ad are by definition substances that are capable of initiating or speeding up a chemical reaction. Catalyst are not a necessity during a chemical reaction‚ they are just used to speed up a chemical reaction. This event
