Introduction: Enzymes are a substance produced by a living organism that acts as a catalyst to activate a specific reaction. The purpose of this experiment was to figure out if the temperature of the reaction would rise‚ will the absorption rise as well. Reactions use energy‚ If there is energy than heat occurs. The Hypothesis that was figured out was‚ If the temperature rises‚ then the absorption will also go up. The Independent variable that was tested was temperature. The dependent variable that

[2] In 2012‚ Cadillac’s U.S. sales were 149‚782 vehicles.[3] Cadillac is among the oldest automobile brands in the world‚ second in America only to fellow GM marque Buick. The firm was founded from the remnants of the Henry Ford Company in 1902‚ almost 9 years before Chevrolet.[4] It was named after Antoine Laumet de La Mothe‚ sieur de Cadillac‚ who founded Detroit‚ Michigan. The Cadillac crest is based on his coat of arms. By the time General Motors purchased the company in 1909 Cadillac had already

8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on

substrate concentration‚ the enzyme is working at “maximum efficiency.” With a concentration at 40‚ it produced 2‚339 products. 2. The maximum velocity of a reaction is reached when the active sites are almost continuously filled. Increased substrate concentration after this point will not increase the rate. The reaction rate increases as substrate concentration is increased. It will soon level off though. 3. When the concentration is at low substrate‚ most of the enzyme molecules are not filled
