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‚

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

Influence of Concentration on the Activity of Amylase Title Influence of Concentration on the Activity of Amylase Abstract Does more or less concentration speed up the reaction rate of amylase in starch? In this experiment diluted solutions of amylase were created and then tested using a starch solution‚ I2KI for reaction times. The answer to the question was proved to be that more concentration of amylase speeds up the reaction time. Introduction The enzyme‚ amylase is found in the saliva

Title: Catalase enzyme detection Objective: To understand the function of catalase in cells that produce the enzyme‚ interpret the results of a catalase test and know their value in differentiating bacteria. Materials: 1 clean microscopic slide‚ 3% H2O2 solution‚ swabs. Micrococcus luteus‚ Enterococcus faecalis‚ patient G Procedure: 1) Scrape some cells off from each bateria to the slant and place them on glass slide. 2) Place one or two drops of H2O2. Watch for bubbling as an indication of

Potato Enzyme Lab Enzymes are protein catalysts that speed up chemical reaction in living organisms. The purpose of this lab was to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added

The Activity of a Protease (Trypsin) Introduction Enzymes catalyze reactions by creating alternate reaction mechanisms whose transition states are more thermodynamically stable than uncatalyzed reactions (Berg et al.‚ 2002; UBC Department of Microbiology and Immunology‚ 2006). Increased thermodynamic stability in these transition states reduces the energy of activation‚ the minimum amount of energy input a chemical system requires for a reaction to occur (UBC Department of Microbiology

FUNCTIONS OF ENZYMES Enzymes are extremely important to the human body and its ability to function. An enzyme itself is a protein made by the body’s cells to act as catalyst‚ speeding up chemical reactions in the cell. It does this by taking the reactants‚ or the elements or compounds that enter into the chemical reaction‚ in this situation referred to as substrates‚ and breaking apart their bonds so that new ones can form. The three types of enzymes are digestive enzymes‚ food enzymes‚ and metabolic
