the rate in which Amylase breaks down starch into maltose. In this reaction starch is the substrate and maltose is the product. Amylase is an enzyme‚ Enzymes‚ also called catalysts‚ are in living things and there are thousand of them. Enzymes break down food by the active site on the Enzyme forming a chemical bond with a substrate and then water attacks the substrate until it is hydrolysed (split in 2).

Abstract: This experimentation was to evaluate absorbance and the reaction rate of an enzyme‚ ’-amylase in starch-iodine solution. We will be testing the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures‚ and different pH levels; it would determine at which temperature and pH level the enzyme worked the most efficiently. Analyzing absorbance of the solutions with spectrophotometery will determine the reaction rate. To

substrate that will form its products. The purpose of the experiments is to determine the effects of substrate concentration‚ reaction time and enzyme concentration on the direction of an enzyme reaction. Amylase is a digestive enzyme found in both the saliva and the small intestine. Salivary amylase is a hydrolytic reaction that breaks down starch molecules by systematically breaking off the maltose molecules from the ends of starch chains. The maltose is further broken down by another enzyme. Phosphorylase

Concentration on the Activity of Amylase Title Influence of Concentration on the Activity of Amylase Abstract Does more or less concentration speed up the reaction rate of amylase in starch? In this experiment diluted solutions of amylase were created and then tested using a starch solution‚ I2KI for reaction times. The answer to the question was proved to be that more concentration of amylase speeds up the reaction time. Introduction The enzyme‚ amylase is found in the saliva of most

enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them to become sweeter‚ and also during the germination of cereal grains. Grain amylase is key

Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually iodine has a orange-yellow

Amylase is found in the saliva of humans and is responsible for the first step in breaking down starch. Starch is a polysaccharide composed of a large number glucose monomers joined together. Amylase breaks down starch by separating the glucose molecules into maltose‚ which is a two glucose-unit compound. (Morgan‚ 2008) During this experiment we investigated the influence of pH on the activity of the enzyme Amylase. We are able to use the fact that when I2KI
