enzymes so a reaction can occur. For example, sucrose (substrate) fits into sucrase (enzyme) where hydrolysis occurs consequently splitting sucrose into glucose and fructose. However, in our experiment, we used the enzyme amylase which hydrolyzes starch into simple sugars like glucose. In the experiment, we prepared seven test tubes two of which were control. One control contained zero milliliters of amylase, one milliliter of water and three…

carbohydrates can be starch, sugar, and fiber. Carbohydrates can either have simple or complex forms. For example, glucose, a sugar, is a monosaccharide; these are carbohydrates in their simplest form (Timberlake, 2006). When only a few of these monosaccharide are linked together, they create oligosachharides. If many of the monosaccharides are bonded, they create polysaccharides. These are considered complex carbohydrates. A polysaccharide which is made up of amylose and amylopectin would be…

Thermoplastic starch is a biodegradable polymer mixture which is biologically degradable and has also a great mechanical and thermal properties. Thermoplastic starch is made by blending starch with a plasticizing agent such as sorbitol or glycerol to make thermoplastic melt. This is why thermoplastic is non harmful to humans, it contains non toxic materials…

hypertonic animal cell will undergo osmosis and release water eventually causing the cell to shrivel up and shrink. Both of these results make it extremely important for animal cells to reach equilibrium or isotonic levels. Place 4 full pipettes of starch into a small beaker. Use a pipette to add 4 pipettes of α-amylase to the small beaker then stir. Open dialysis tubing from one end then tie the tubing with a clamp. Open the moist end and add 4 pipettes of the solution from the beaker into the…

amylase and its corresponding substrate was starch, by binding together amylase was able to break down starch into maltose. The question of interest of this experiment was whether or not temperature would affect the rate of enzymatic activity, this was observed by measuring the amount of starch that was digested by amylase at varying temperatures.…

Introduction: A human has thousands and thousands of different proteins, each with a specific structure and function. Along with their diverse functions, they vary in structure, each protein having its own unique three-dimensional shape. Proteins are polymers of amino acids joined together by peptide bonds. There are 20 different amino acids to make up all the different proteins on the earth. Each of the amino acids is composed of a central carbon bonded to a hydrogen, a carboxyl group, an amino…

substrate binding and hating the reaction (Kopaleishvili, 1995). At lower temperatures, the energy of particles is lower and there are less collisions. Therefore, at 0oC the particles were barely colliding as they had reduced energy and the hydrolysis of starch took longer than 24 minutes, however. At 20oC the enzymes are gaining more energy and they are colliding more until they reach the optimal amount of energy per particle at 40oC and are reacting the fastest. At 80oC the enzymes are…

took the longest time for the starch to disappear (10 mins 30 seconds). This means that at the temperature of 4°C amylase activity are the slowest, it takes longer for the starch to get digested. On the other hand when amylase was in the temperature of 80°C in tube one, starch disappeared much quicker (1min). This means that amylase acts quicker in a higher temperature. The body temperature for human is between 36°C to 37°C, which means it utilizes digestion of starch rate in a way that's not…
