the function of enzyme catalysed reactions (inhibitors not required) (10) There are four main factors that affect the rate of reaction on enzyme-catalysed reactions. The first of these is temperature. When increasing the temperature of a reaction the kinetic energy of molecules increases and therefore they more around more quickly and collide with each other more often. This means that within an enzyme-catalysed reaction the substrate molecules collide more often with an enzyme and so the rate

Kevin Lopez 03/18/13 (008945285) Succinate Dehydrogenase Enzyme Activity in Mitochondrial Fraction Succinate dehydrogenase (SDH) is an enzyme that catalysis the oxidation of succinate to fumarate in the citric cycle. During this step, electrons removed from succinate directly reduce an electron acceptor, known as FADH2; however, for this laboratory experiment an artificial electron acceptor, dichlororphenolindophenol (DCPIP), was utilized. By inhibiting complex IV of the electron transport chain

Effects of Different pH Level on Amylase in Starch Introduction Amylase, a family of proteins that differ in isoforms, is a digestive enzyme found in saliva and pancreatic fluid that helps digest starch into simple sugars. (Scannapieco et. al., 1993). Amylase is the first step in digesting starch, which is used for the intake of carbohydrates or energy in humans. (Butterworth et. al., 2011). Amylase functions in the hydrolysis of starches, which produces glucose monomers. (Karp, 2010). This

Nguyet Vu Activity of the Porcine Pancreas α-Amylase Enzyme Under Different Concentration Introduction: Enzymes are specialized protein structures that increase the rate of reactions without changing chemical equilibrium between reactants and products (Cooper, 2000). These enzymes have a distinct chemical composition that constructs an active site for substrates to bind to; this is the location where the substances come together to from an enzyme-substrate complex, which makes forming a product possible

Temperature, pH and Enzyme Concentration on Enzymatic Activities 1. Introduction Enzymes are biological catalysts that are protein. They speed up the rate of chemical reactions and metabolism in the body of organisms. They are specific in their action that means a certain enzyme will only speed up a certain reaction involving a specific substrate to bring about a specific product. Enzymes work on a key and lock mechanism where substrates are linked to their active sites. Enzymes reduce the activation

Lab13: *Evolution: change in allele frequencies in a population over time * The population does not occur if: A. The breeding population is large. The effect of a change in allele frequencies is reduced. B. Mating is random. Organisms show no mating preference for a particular genotype. C. There is no net mutation of the alleles. D. There is no migration or emigration of organisms. E. There is no natural selection. Every organism has an equal chance for passing on their genotypes. Dom

WGU GRT1 208.5.4- 01-07 Enzymes are proteins that are catalysts for biological processes. The enzymes can slow down or speed up a biological reaction. Enzymes have an active site, which have different shapes for different functions it is to perform. A reaction will begin when a substrate with the matching shape connects to the enzyme. It is critical that these pieces correctly fit together in order for the process to run smoothly and complete its job. Enzymes help break up large molecules faster
