Enzyme Lab Using Jello INTRODUCTION: Enzymes are known as protein catalysts. The name protein catalyst suggests that most enzymes are made of proteins. A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe‚ M 2002‚ p.69). After a reaction has been catalyzed‚ the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place. Enzymes can either catabolize

Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

Principles of Biology Lab Exercise Enzymes: Catalysts of Life Instructor: Professor Alcendor By Shahid Rana Date: March 7th‚ 2013 Abstract: In this experiment we have demonstrated the function of enzymes. The whole experiment was devoted to understand how enzymes work as a catalysts and increase the chemical reaction without being used themselves. In general‚ enzymes are proteins that function as biological catalysts. These enzymes adhere to lower to amount of energy required for

Ayaan Nadeem SBI 4UO-A Tuesday‚ February 27‚ 2013 Ms. Balmer Pineapple Jelly Enzyme Lab Discussion After completing the Pineapple Jell-O Enzyme lab‚ the final results were that the canned pineapple formed the jelly while the fresh pineapple did not. Pineapple In order for this to have occurred‚ there has to be a comparison between fresh and canned pineapple in terms of their physical and chemical properties. The physical properties of fresh pineapple are that it is sweet‚ ripe and raw.
