experiment we compared the hemagglutination reaction of control Con A solution at 2 mg/ml in Con A buffer with the hemagglutination reaction of your own purified Con A sample that you diluted previously at 2 mg/ml in Con A buffer. The purpose of this lab was to determine the strength of the reaction by performing serial dilutions on both the Con A sample and the control Con A sample‚ and determine through observations whether or not addition of galactose or mannose will inhibit this reaction. I hypothesize

Explain the mechanism of communication‚ control‚ and integration in the endocrine system. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it

The purpose of this review paper is to discuss the effect of temperature on enzyme- catalyzed reactions. This is relevant because many diseases can be diagnosed and controlled by the processes of enzyme activity (Worthington 2015). If more information is not found about enzyme activity and how it is affected‚ many diseases may go undiagnosed and uncontrolled. Temperature is a type measurement that does not only consist of heat. It is the measurement of the mean kinetic energy of any group of particles
Premium Enzyme Chemical reaction Catalysis
Structure: Enzymes are globular proteins that act as catalysts‚ they have a specific 3D shape that is the result of their amino acid sequence. There is a specific region of the enzyme that is functional‚ this is called the active site. The active site is made up of a small number of amino acids and forms a small depression within the larger enzyme molecule. Moreover‚ the molecule that the enzyme acts upon (substrate) fits precisely into the depression and forms an enzyme-substrate complex. The substrate

Adam Berg May 5th‚ 2013 Synthesis Essay – “I Grew Up” and “Night” “I Grew Up”‚ by Lenore Keeshig-Tobias‚ and “Night”‚ by Yvonne Trainer‚ are two poems which tell of two children’s upbringings‚ one which was described as “the most beautiful place”(1‚ 3rd line)‚ and one that was filled with anger and abuse. Both of these poems confront‚ and defy the generic stereotypes commonly associated with Native American reserves and traditional American family farms. Lenore’s poem focuses on a

in these reactions‚ resource‚ products and enzyme are three most mainly things. In all chemical reactions‚ there is a activation energy(EA) needed for them. However‚ if the rate of reactions are too low‚ they will not be able to sustain lives. In this case‚ they have enzyme as a protein catalyst. As reaction catalysts‚ enzymes are proteins that adjust the process by initiating the reaction. In this case‚ there are also many elements that influence enzyme working rates. For example‚ most living things
