temperature on the activity of lipase Aim: To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This experiment is carried out to find the

hold another paperclip at the appropriate distance: six cm‚ seven‚ eight‚ nine‚ ten‚ twelve‚ fourteen‚ sixteen‚ eighteen‚ and twenty centimeters. 5. Lab partner must close eyes tightly. 6. Starting with the largest distance‚ place either one or two ends onto your partners skin (ALTERNATE RANDOMLY so the partner can’t guess!!!) 7. Have lab partner tell you how many ends they can feel. Do this 5 or 6 times. 8. Then try the next smaller distance and repeat steps 6 and 7. 9. Record

Enzymes What Are Enzymes? Substances that speed up chemical reactions are called catalysts. Organic catalysts are called enzymes. Enzymes are specific for one particular reaction or group of related reactions. Many reactions cannot occur without the correct enzyme present. They are often named by adding "ase" to the name of the substrate. Example: Dehydrogenases are enzymes that remove hydrogen. Induced-fit Theory The shape of the enzyme must match the shape of the substrate

Enzyme action is the simple mechanism by which enzymes catalyse chemical reactions. This begins with the binding of the substrate to the active site on the enzyme. The binding of the substrate to the enzyme causes changes in the distribution of electrons in the chemical bonds of the substrate. This then causes the reactions that lead to the formation of products that are then released from the enzyme surface to regenerate the enzyme for another reaction cycle. The active site has a unique shape that

Introduction: Enzymes are biological catalysts that permit cells to carry out the many functions that are required in a living system. Every enzyme has a specific substrate and a specific function. Enzymes alter substrates one of three ways: by adding something to the substrate‚ removing something from the substrate‚ or by changing its conformation‚ otherwise known as its shape. The structure of an enzyme and its ability to function exists because it binds to an active site‚ thus increasing the

Factors Affecting The rate of Enzyme Activity Prediction: As the temperature increases the rate of enzyme activity will also increase‚ thus increasing the rate of reaction. However‚ if the temperature is too high the enzyme will denature.

Erin Arroyo Lab report June 11‚ 2013 Biology 123 Professor K Title: Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature

PH level of Amylase Background info: What is Amylase? Amylase is an enzyme that helps digest carbohydrates. It is produced in the pancreas and the salivary glands. (Dugdale & Longstreth‚ 2011) Factors Affecting Amylase: Things that affect the efficiency of Amylase are temperature and pH levels. (Wikimedia Foundation‚ Inc‚ 2013) Function in the body: The function of Amylase in the human body is to break down plant-based starch sources. Therefore‚ providing the human body with more

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The
