How Does Temperature Affect Lipase

How does temperature affect the rate of reaction for Lipase? As the temperature increases, so will the rate of enzyme reaction. However, as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately 37°C. I predict that before the optimum temperature the rates will gradually increase and preceding the optimum there will be a drastic decrease in rate until the enzyme is denatured. I predict that the rate of enzyme activity at 45°C will…show more content…
[An active site can be altered by a non-competitive enzyme which encircles the enzyme and alters the shape of the active site which could be very dangerous.] Diagram courtesy of: http://www.wiley.com/college/boyer/0470003790/reviews/kinetics/kinetics_effectors.htm Diagram courtesy of: http://www.wiley.com/college/boyer/0470003790/reviews/kinetics/kinetics_effectors.htm Note that the enzyme remains unchanged so that more of the some substrates can react. Note that the enzyme remains unchanged so that more of the some substrates can react. Structure Proteins are polymers made by joining up small molecules called amino acids. Amino acids and proteins are made mainly of the elements carbon, hydrogen, oxygen and nitrogen. Protein Protein Amino Acid Amino Acid Each gene acts as a code, or set of instructions, for making a particular protein. They tell the cell what to do, give its characteristics, and determine the way its body works. Each protein has a unique sequence of amino acids. This means that the number and order of amino acids is different for each type of protein. The proteins fold into different shapes. The different shapes and sequences give the proteins different functions, e.g. keratin are a fibrous protein found in hair and nails. If the gene has even the slightest of disorder within its sequence it could lead to an inaccurate order of amino acids
