Introduction The human body is kept alive due to an immeasurable amount of chemical reactions that occur in perfect synchronization. Also‚ these reactions take place at an incredibly fast rate; however‚ without enzymes‚ these reactions could possibly take several years to complete. An enzyme is a macromolecule‚ generally a protein‚ that lowers the activation energy of a reaction without being changed by the reaction‚ and this causes the reaction to occur much faster than usual (Campbell et al.

Investigating the Enzymatic Activity of Catecholase through Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration University of Alabama at Birmingham Burgess‚ B.N. Introduction: Background Enzymes are macromolecules that act as catalysts in living organisms by speeding up chemical reactions without being changed or destroyed by the reaction (Campbell and Reece‚ 2008). Enzymes are able to speed up the rate of a chemical reaction by decreasing the activation energy during the reaction

In enzymatic activity‚ the molecules at the beginning are called substrates. Lactose metabolism is when lactose is destroyed‚ maintained or produced. For instance‚ being lactose intolerance that’s where lactose is destroyed. Metal cofactors in enzyme activity are required to function properly. The Effect of Temperature on Enzymatic Activity: Based on what I know about the effect of temperature on enzymatic activity‚ at 0 degrees Celsius I hypothesize that there will not be much enzymatic activity

Groups 2‚ 4‚ 6‚ 8‚ 10‚ and 12 completed the test with PMA treated HL-60 cells and groups 3‚ 5‚ 7‚ 9‚ and 11 completed the test with DMSO treated cells. Zymography testing shows the enzymatic activity by showing varying colored bands. During the test‚ the MMPs eat away the gelatin just as they would eat away the extracellular matrix if they were in a living organism and as they eat away the gelatin the color begins to fade away and

2601 21 October 2012 Mood in Porphyria’s Lover Robert Browning uses powerful moments of personification and imagery that linger in a reader’s mind. However‚ the one craft that truly stands out is the mood of the poem. Browning uses specific word choice‚ imagery‚ and tone to shape the mood into what can best be described as haunting. Given the topic of the piece‚ the reaction to find the piece haunting only seems natural. But Browning uses some very interesting ways to make a reader slightly uncomfortable

In the letter by Elizabeth Barrett Browning‚ an English poet‚ she supplicates to Napoleon III to reinstate Victor Hugo back into France after getting exiled due to his writings being seen as offensive toward the government. The intended purpose of the letter is to change Napoleon’s mind about exiling Hugo from France‚ in order to retain one of the most admired and impressive poets from France. Through the use of parallel structure and reverent tone Browning creates reasoning on why the Emperor of

Robert Browning is a poem about a woman being engrossed by jealousy. Browning uses many literary techniques to show the escalating changes of the main character. Through the tone‚ persona‚ and figure of speech‚ Browning utilizes these three elements in order to create the envious nature of the woman in the poem. The poem begins with a tone that is filled with resentment‚ which also describes the speaker’s emotions that soon escalates erratically. The first sign of resent is when browning states:

Based on what I know about the effect of temperature on the enzymatic activity of lactase‚ I hypothesize that higher temperatures will cause denaturing in the enzyme causing it to be less effective and lower temperatures will more conducive to enzymatic activity‚ and a higher pH will be more conducive to enzymatic activity.
