Ap biology lab two: enzyme catalysis - download as word doc (doc), pdf file (pdf), text file (txt) or read online. Enzymes are a form of proteins that act as catalysts to speed up chemical reactions without being consumed by the reaction enzymes bond with substrates and react with the substrates to release productstwo important components of enzymes are their active sites, where the actual substrates bind, and the allosteric sites, which affect the enzyme.
Enzyme catalysis alternative 2 this laboratory exercise is presented as an alternative to the traditional ap catalysis lab the technique is easier for the students to use and yields better results we use fly vials stoppered with one-hole rubber stoppers. Enzyme catalase lab an enzyme, which is a protein, acts as a catalyst of chemical reactions that takes place in the body however, as enzymes are exposed to different environments, their performance is affected in this experiment. Name: date: ap biology lab : factors influencing enzyme activity background enzymes are biological catalysts capable of speeding up chemical reactions by lowering activation energy. The liver: helping enzymes help you a fun chemistry challenge from science buddies by science buddies on march 8, 2012 share this shows that the liver enzyme catalase is working to start the chemical reaction that breaks down the hydrogen peroxide that would be harmful to the body into.
Teacher guide unit this lab fits in chapter 2 (chemistry of life) of freshman biology with enzyme activity overview in this lab, students will use yeast as a source of catalase. Lab 2: enzyme action enzyme action—effect of enzyme concentration, temperature and ph on catalase activity prelab assignment before coming to lab, read carefully the introduction and the procedures for • define enzyme, catalyst, active site, substrate, activation energy. Catalase lab a bio enzyme activity laboratory gen nelson introduction hydrogen peroxide (h 2 o 2) is a poisonous byproduct of metabolism that can damage cells if it is not removedcatalase is an enzyme that speeds up the breakdown of hydrogen peroxide into water (h 2 o) and oxygen gas (o 2) 2h 2 o 2-----catalase----- 2h 2 o + o 2. Lab 2 enzyme catalysis introduction: enzymes are proteins produced by living cells they are biochemical catalysts meaning they lower the activation energy needed for a biochemical reaction to occur because of enzyme activity, cells can carry out complex chemical activities at relatively low temperatures.
