temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction temperature of amylase solution

The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

sucrose‚ 1%lactose‚ 1% glycogen‚ 1% starch‚ protein‚ beer‚ distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine into starch‚ the result was the starch solution turned dark blue. Starch had a positive result is because of the complex of iodine stuck inside the amylase coil which produced a characteristic

Bread contains starch. The starch content in bread is derived from the starchy endosperm of wheat. Refined breads have the bran and germ removed from the wheat in order to produce softer‚ silkier flour. there is a lot more food containing starch like: Starchy foods such as potatoes‚ bread‚ cereals‚ rice and pasta should make up about a third of the food you eat. Where you can‚ choose wholegrain varieties‚ or eat potatoes with their skins on for more fibre. Starch is the most common form of
