Modeling Effective Dose: Salt Tasting lab Purpose The purpose of this lab is to see at what measurements (of salt) can the salt be detected by taste. Abstract The science of toxicology is based on the principle that there is a relationship between a toxic reaction (the response) and the amount of poison received (the dose). An important assumption in this relationship is that there is almost always a dose below which no response occurs or can be measured. A second assumption is that once a maximum

SU_BIO2071_W1_A2_Alimole_. A.doc. Exercise 1: Hanging-drop and wet-mount preparations How does true motility differ from Brownian movement? Brownian movement is the result of molecules of the suspending water bumping into the bacterium. This is an asymmetrical‚ spasmodic movement‚ which gives cells a vibrating look. This does not show proper motility. Correct motility is movement in a specific constant direction that shows winding and spinning. What morphological structure is responsible

Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

Structures‚ Biosynthesis and Biofunctions of Iron-sulfer proteins Yiming Chen‚ Brown University‚ May 11th‚ 2011 I. Introduction Iron-sulfur proteins are the proteins which contain iron-sulfur clusters‚ like sulfide-linked di-‚ tri-‚ and tetrairon centers with various oxidative states 1. An excess of 120 distinct types of enzymes and proteins are known to contain Fe-S clusters2. Iron-sulfur proteins are known for the role of the oxidation-reduction reactions of mitochondrial electron transportation

Nupoor Matieda October 10‚ 2014 PD 9/10 Lab Report Separation of a Mixture of Sand and Salt Goal(s): To separate a mixture of sand and salt and to find the percent of each component by mass of each mixture Background Theory: A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties. Mixtures can be separated by physical processes such as filtration and evaporation. Filtration is a process where solids

The substrate molecule is held into the active site by bonds that temporarily form between certain amino acids of the active site and groups on the substrate molecule. Enzyme-substrate complex: The enzyme-substrate complex formed when the enzyme binds with its substrate lowers the activation energy (minimum amount of energy needed to activate the
