structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

adding a molecule of water to a peptide bond. Although the hydrolysis reaction is thermodynamically favoured in the absence of a catalyst the half-life for a typical hydrolysis reaction by a protease is between 10 and 100 years‚ needless to say it is extremely slow1. Though this is true peptide bonds are hydrolysed within milliseconds in the body in the presence of catalysts. The kinetic stability of chymotrypsin which gives it hydrolysis resistance is due to the resonance structure that accounts for

and Hydroxylamine on the Enzyme Peroxidase Extracted From Brassica rapa Abstract In this experiment the enzyme peroxidase was extracted from from a turnip‚ Brassica rapa‚ and tested under different conditions. The effects of temperature‚ boiling‚ pH‚ and a competitive inhibitor were tested. The enzyme was tested at temperatures of 4°C‚ 24°C‚ 32°C‚ and 48°C. As the temperature increased‚ so did the activity of the enzyme. The enzyme was tested at pH levels of 3

[Teacher] [Course] [Date] Catalase Lab Report An enzyme is something that helps to speed up a chemical reaction. The enzyme changes from reaction to reaction‚ but it always has the same impact. However‚ certain variables may cause the enzyme to have a more or less significant impact on the speed of each reaction. One of these variables that changes the effectiveness of an enzyme is temperature. There is an optimal functioning temperature for each enzyme in each reaction‚ depending on the desired

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

experiments are: Lactase Enzyme and Lactose. Lactase is a protein located in the human small intestine‚ while lactose is a term to define the sugar found in milk. Milk is a substance that contains nutrients necessary for our bodies‚ however‚ some people are unable to consume lactose related products‚ and so they are medically classified as Lactose Intolerants. The purpose of this experiment is to examine and illustrate the way that lactose gets affected by lactase enzyme whenever lactase is presented
