Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply

and implement it in the lab. Configure RIP as a routing protocol. Conditions NYEDGE1 is the hub router. The two remote office routers NYEDGE2 and NYWAN1 connect to NYEDGE1 through serial connections. Each router has a locally attached Ethernet network. The serial line data rates and DTE/DCE settings have already been configured on all three routers. You only need to assign the IP address to the interfaces. Notes The routers are connected directly to each other in this lab and do not actually connect

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

reaction can be explosive. 2KMnO4 + 2 H2SO4 → 2 KHSO4 + Mn2O7 + H2O These activities show that different substances catch fire at a different temperature. The lowest temperature at which a substance catch fire is called its ignition temperature. Combustible substances do not catch fire or burn as long as its temperature is lower than its ignition temperature. Now let me do an activity which tells you why reaching ignition temperature is necessary to burn an object. You know that paper catch fire with

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it

How Temperature Affects Amylase Activity Abstract This study of the effect of temperature on the enzyme amylase was performed to determine the relationship between the enzyme amylase and temperature. The rate of reaction was found to increase as the temperature of the environment was raised. As the temperature was raised from 5°C‚ 20°C‚ 35°C and finally to 80°C the rate of reaction followed this trend and also increased. However as predicted in the hypothesis of this experiment when the temperature

Lab Assessment Questions & Answers 1. Define why change control management is relevant to security operations in an organization. Change control is a precision arrangement of managing every change made to a system. This is to ensure that no unneeded changes are done‚ that every change is documented‚ and that no service is disrupted unless absolutely necessary‚ and that all resources efficiently used. 2. What type of access control system uses security labels? A LBA C Label Base Access
