Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

The activity of an Enzyme is affected by its environmental conditions and changing these factors can alter the overall rate of the reaction. Reaction rates are influenced by external factors such as pH‚ temperature and salt concentration. Different enzymes have different optimum temperatures in which they are most efficient and different pH levels which is ideal for their formation of enzyme-substrate complexes. As the temperature increases‚ there is more movement of molecules and more random collisions

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

The Rate of Reaction that Enzyme Concentration‚ pH‚ and Temperatures Have on the Amylase Enzymes Color Disappearance Abstract: Compare reaction rates of the concentrations‚ pH’s‚ and temperatures of the enzyme Amylase. At what concentrates do the substrate molecules collide with each other‚ making the reaction possible? At what pH levels do the 3D molecular structures change breaking the H-bond and/or denaturize? At what temperatures do the collisions of the substrate molecules happen

to see the effects of enzyme concentration on the reaction rate. Part 2: Effect of Substrate Concentration Purpose: The purpose of this part of the lab was to find the effect of substrate concentration on enzyme activity. Part 3: Effect of Temprature Purpose: The purpose of this part of the lab was to determine the effect of temperature on the rate of enzyme activity. Part

Lab 6.C Hypothesis: If enzyme activity is affected by the pH of a solution‚ then the enzymes will experience the greatest activity at a pH of 6. Variables: Independent Variables Dependent Variable Controls Four different pH values (10‚ 7‚ 6‚ and 3) Change in color of the solution The amount of potato extract‚ pH solution‚ and catechol used (1 cm +/- .1cm) Size of the test tubes Amount of time allowed for the catechol to sit with the potato extract and pH solution (20 minutes with 5

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

Enzymes are organic catalysts‚ usually proteins that speed up metabolic reactions. They lower the amount of energy needed for reactions to progress in cells. 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:

I. Preparation A. Choosing 1. You should choose the fruits that you like. a. For example‚ if you desire to gain more different fruits enzymes or make the glass bottle more colorful‚ you can choose four or even more kind of fruits. There is no limitation. But‚ you must include one fruit‚ lemon. It helps to kill the bacteria of the drink. B. Composing 1. The ratio of components should be 3‚ 1. It means 3 parts of fruits‚ 1 part of sugar. You can follow this ratio to determine the amount of fruit
