active site of the enzyme is complementary to the shape and polarity of the substrate. Typically‚ only one kind of substrate will “fit” into the active site. In this experiment‚ we will work with the enzyme amylase. This enzyme is responsible for hydrolyzing starch. In the presence of amylase‚ a sample of starch will be hydrolyzed to shorter polysaccharides‚ dextrins‚ maltose‚ and glucose. The extent of the hydrolysis depends on how long it is allowed to react – if the starch is hydrolyzed completely

Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat

conditions for fungal and bacterial amylase was measured as well. Discovering information‚ such as the optimal temperature‚ can help demonstrate the environment these organisms work best. Thus‚ if further studies are conducted on different enzymes‚ the more information is covered about certain organisms. In the experiment‚ each enzyme source was put to the test by being placed into different test tubes and baths with altered temperatures. In order to see how long the Amylase was hydrolyzing starch in different

Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in

A. Fermentation Lab- The basic process Prepared 3 beakers with contents listed below. ( a. Beaker 1: glucose only b. Beaker 2: Starch only c. Beaker 3: Starch + amylase). Poured contents of each beaker into its respective fermentation tube‚ ensuring the tail portion of the tube was filled with liquid. Placed tubes in an incubator at 37 degrees‚ measuring distance between tip of tube tail to fluid level at 20‚ 40‚ and 60 minute intervals. Calculated gas volume using this distance along with radius
