Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

Biology textbook- pg. 80 3) Distinguish between the autotrophic and heterotrophic nature of plants and animals. Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there

Pre-Lab 1 Assignment Quantitative Analysis of Biomolecules Biochemical analysis involves the characterization of biomolecules within a sample using appropriate laboratory techniques. There are two principal approaches: 1. Qualitative analysis – where a sample is analyzed to determine whether a biomolecule is present or absent. As an example‚ a blood sample might be analyzed for a specific antibody or a bacterial cell might be probed for a nucleic acid sequence. 2. Quantitative analysis
