20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that specific enzyme. The place

Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks

Introduction How does changing the surroundings of enzymes affect their reaction rate? The purpose of the experiment is to determine how different abiotic conditions affect the rate at which enzymes accelerate/cause reactions In this lab students measured the height of the foam after catalysis between catalase (enzyme) and 7 other (solutions) to determine which solution had the fastest reaction rate.. The control variable of the experiment would be the solution of only hydrogen peroxide‚ water

The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
Premium Enzyme Chemical reaction Chemistry
Enzymes are proteins or nucleic acids that catalyze reactions. They are able to speed up reactions by reducing the activation energy of a reaction. Each kind of enzyme has a specific shape that matches its substrate so it can bind to its active site. Enzymes convert their substrates into a product. Enzyme activity are affected by factors such as temperature‚ pH‚ and time. If an enzyme is exposed to extreme heat‚ it will become denatured‚ that is‚ to become deformed and lose its original shape which

Lab 4 Quiz 1. Enzymes and what is their function? a. Enzyme: biological catalysts that regulate chemical reactions that occur in cells. Responsible for things such as converting food to energy‚ replace old damaged tissues‚ disposal of cellular waste products. Are responsible for lowering the activation energy. 2. Most enzymes are proteins with three-dimensional shapes determined by their amino acid sequence. 3. Substrate – is a reactant molecule that binds to the highly specific active site
