10.10.2012 Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the

Enzymes: Food & Nutrition What are enzymes Enzymes are a type of protein produced by a living organism used to catalyze chemical reactions in cells. These reactions allow the cell to build things or take things apart as needed in order to grow and reproduce. How do enzymes work - in steps 1) Substrate floats near enzyme 2) Substrate and enzyme connect – which breaks it into products 3) Products are released ex) BreadFast & Co.’s use of enzymes The company uses many different

The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction

Enzyme Assignment Research SBI4U Test A2 Table of Contents 1. What are the function roles and biological significance of the enzyme? Trypsin is part of the digestive system and degrades proteins‚ making it an enzyme known as protease. [1] It is one of the three principal digestive proteinases‚ the other two being pepsin and chymotrypsin. [9] Trypsin primarily hydrolyses peptides into smaller building-blocks‚ mainly amino acids (these peptides are the result of

Biology‚ Section G 27 September 2013 Experiment 5.3 Title: The Fragility of an Enzyme Purpose: To see how easily enzyme function can be destroyed. Hypothesis: I think that the bowl with only Jell-O will set as will the bowl with heated pineapple but the Jell-O with fresh‚ uncooked pineapple will not set. Materials: Part of a fresh pineapple A blender or a fine cheese grater 3 small bowls A small box of Jell-O Pot Stove Refrigerator 2 tablespoons Procedure: 1. Cut the pineapple

Temperature affecting enzyme activity Aim: To see how temperature can affect enzyme activity Prediction:-I think the one that will work best will be the rennin placed in milk at 37oC My independent variable will be the temperature My dependant variable will be how thick the milk becomes The equipment I need is milk‚ 5 test tubes‚ rennin‚ water bath‚ boiled rennin‚ a glass rod and a stopwatch Introduction: Rennin is an enzyme found in the stomach‚ its function is to solidify milk. We

15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site of enzyme to transfer in to one or

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

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved
