Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time

Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme converts them

1.7 Factors that affect the activity of an enzyme It is important when working with enzymes to understand basic enzymatic theory behind them when selecting conditions to measure the activity of the enzymes. The factors that are known to affect the concentration of enzymes are temperature‚ pH‚ concentration of enzyme‚ concentration of substrate‚ buffer type and concentration‚ the presence of any inhibitors and cofactors (Worthington-biochem.com). 1.7.1. Temperature With most catalysed reactions‚

structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell and is named according to the substrate they specifically affect. An enzyme works best under optimal conditions pertaining to temperature‚ pH level and salt concentration1. In unfavorable conditions enzymes will become denatured and ineffective

The purpose of the experiment was to find out how temperature affects the enzymes activity. For example‚ in Humans if the temperature is too high‚ the individual’s brain enzymes can denature and cause life threatening problems. The opposite can occur as well‚ if the temperature is too low‚ hypothermia can occur and it can be dangerous (Wilson‚ 1996). In the experiment optimal conditions for fungal and bacterial amylase was measured as well. Discovering information‚ such as the optimal temperature

Title: The Effect of Varying Amounts of Substrate and Enzyme on a Reaction Rate Abstract In living organisms‚ certain reactions must take place rapidly to assist life. This occurs because of enzymes‚ because all reactions would take place too slowly to sustain life (Jacklet‚ 237). Enzymes are large protein molecules that catalyze specific chemical reactions without being used up in the process. Each enzyme has a region on its surface‚ called the active site‚ which recognizes a specific

Abstract: After reviewing the basics of enzymes and catalysis‚ we take a dive into the wonderful world of catalase. Beginning with establishing a base line of just how much hydrogen peroxide there is in 5.0mL of the reacted solution; to figuring out exactly how much actually reacted after 300 seconds of catalyzed reaction. Follow the experiment from the beginning steps right to the end as you see where the students went wrong‚ interpretation of the results‚ and great answers to work sheet

Chemistry Unit 1 – Revision Questions Chemistry 1A 1) Define an element. How many are there in the Periodic Table? 2) Write a table with the charges and masses of protons‚ neutrons and electrons. 3) Define atomic number and mass number. 4) Draw electron (energy level) diagrams for Be‚ S‚ Al‚ Cl and K. Also‚ write down the number of protons and neutrons for each. Finally‚ write the symbols (with mass no. and atomic no.) 5) Why have all Group 7 elements (halogens) got similar chemical properties

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The
