enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for protein substrates. In the same way amylase is a specific

INTRODUCTION Isolation of Aspergillus niger from garden soil for the production of amylase enzyme and effect of various parameters on enzyme‚ production is the main aim of this study. Enzymes are protein catalysts synthesized by living systems and are important in synthetic as well as degradative process. Amylases are starch degradative enzymes that catalyze the hydrolysis of internal a-1‚ 4-0-glycosidic bonds in polysaccharides such as starch in to simple sugar (glucose and maltose). It is produced

Practical: The effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases‚ the enzyme activity increases

Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected

Alpha amylase is an enzyme that aids in the breakdown of starch and glycogen to form glucose and maltose through the hydrolyses of alpha linked polysaccharides1. Starch is a complex carbon and is the main energy storage material found in plants and some bacteria. It is a major component of food as it supplies plants with energy and carbon. Starch consists of two types of polysaccharides called amylose and amylopectin1.The properties of starch can depend on the number of alpha 1‚4 glycosidic bonds

If the amylase successfully digests the starch‚ what results would you expect? If the amylase successfully digests the starch‚ I would expect a no color change occur as well as a presence of glucose in the intestine (Dialysis tubing). If the amylase only partly digests the starch‚ what would you expect to happen? If the amylase only partly digests the starch‚ I would expect to see a faint color change as well as a small presence of glucose inside the intestine. If the amylase fails to
