Effecting the Reaction Rate in Enzymes in Plants and Animals Problem- How do variables temperature and surface area affect the rate of reaction occurring in the enzyme? Information- Enzymes are proteins that act as biological catalysts. They speed up chemical reactions that take place in cells. Enzymes can be found in both liver and potato. They provide a site where reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing of heat‚

HETEROGENEOUS CATALYSIS D. C. AGUILAR AND B. N. SANCHEZ INSTITUTE OF CHEMISTRY‚ COLLEGE OF SCIENCE UNIVERSITY OF THE PHILIPPINES‚ DILIMAN QUEZON CITY‚ PHILIPPINES RECEIVED MARCH 17‚ 2008 ABSTRACT Catalysis which involves the use of a catalyst in a different phase from the reactants is known as heterogeneous catalysis. Catalysts are known to enhance rates of reaction without being consumed and they also reduce activation energies. The hydrogen peroxide decomposition reaction catalyzed

Lab Report Enzymes (must be typed) Name: Amanda Gallegos Date: 2/15/15 Section: BIOL 101GL What is the Hypothesis of this experiment? (3 points) -The highest temperature will affect the reaction rate of enzymes. What is the dependent variable? (1 point) -Change of rate/product/color/absorbency. What is the independent variable? (1 pt) -The temperature. Explain in detail the procedure that you followed (including amount of substrate‚ enzyme etc‚ and the whole procedure including incubation times)

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

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

Biofuel Enzyme Kit Katie Adamson Biochemistry Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

Ah Seung Chong Molecular Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction

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

Enzymes INTRODUCTION Enzymes are protein cells and they are found in the gut. They help to break down the food you eat. Enzymes are produced by living cells and they speed up reactions because they are biological catalysts. If we did not have enzymes‚ the reactions in our cells would be too slow to keep us alive. This means that they are extremely important for our survival. The properties of enzymes are: ⋆ They can be used many times‚ because they can speed up reactions without
