“Comparing Average Rates of Respiration in Mealworms in Light and Dark Environments in a Manometric System” Mohammad Rafi 213552179 BIOL1000 LAB REPORT Oct 28‚ 2014 Hypothesis The biological hypothesis for this lab experiment was that the rate of respiration in mealworms would decrease in mealworms that were exposed to a dark environment compared to those mealworms that were exposed to a light environment. This hypothesis was based on the fact that oxygen levels tend to decrease in

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of catalysis such as an enzyme. Moreover to

The Effect of Different Types of Insulation on Heat Retention Aim I am going to investigate the effect of different types of material on heat retention. "Which of the four materials‚ cotton‚ foam‚ aluminium foil and bubble wrap‚ is the best insulator?" Hypothesis The four materials tested in this experiment are cotton‚ foam‚ aluminium foil‚ and bubble wrap. Materials that are good insulators will absorb heat slowly and therefore the water inside the cup will stay warm for

Enzyme assay lab report Health and safety: 4-nitrophenol is harmful. Introduction: Enzymes are quaternary structured proteins that are specific biological catalysts that speed up a reaction without being used up. They contain an active site that allows substrate to bind to a specific area on the enzyme which is of a complimentary shape of the substrate. There are two models of enzyme action‚ the Lock and Key model and the Induced Fit model. The Lock and Key model states that the enzyme has a specific

amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal pH. The pH affects the charge of the amino acid at the active site. PH changes affect the structure of an enzyme molecule and therefore affect its ability

Email: femijohn@gmail.com 43 INTRODUCTION The roles of metal ions in metalloenzymes include direct participation in catalysis‚ stabilization of protein structure and regulation of enzymatic activity. Membrane alkaline phosphatase (ALP) is a metal-containing enzyme that serves as a good model for the study of metal ion interactions in enzyme catalysis. Native E. coli ALP contains three

Enzymes (pron.: /ˈɛnzaɪmz/) are large biological molecules responsible for the thousands of chemical interconversions that sustain life.[1][2] They are highly selective catalysts‚ greatly accelerating both the rate and specificity of metabolic reactions‚ from the digestion of food to the synthesis of DNA. Most enzymes are proteins‚ although some catalytic RNA molecules have been identified. Enzymes adopt a specific three-dimensional structure‚ and may employ organic (e.g. biotin) and inorganic (e
