Properties of Enzyme Catalysts - UK Essays.
Enzymes are globular shaped proteins that are found throughout the body, with their main function being to act as biological catalysts. An enzyme can act to speed up or regulate the rate of the reaction, in order to maintain an efficient rate of biological reactions.
An enzyme is a catalyst that speeds up the rate of reactions by lowering the activation energy. Each enzyme works better under optimal conditions, which favor the most active shape for the enzyme molecule. Enzyme and substrate concentration, temperature, and pH are environmental factors important by producing the most reaction rate.
Enzyme works better under optimum conditions including enzyme concentration, substrate concentration, temperature, and pH because they favor the most active form for the enzyme molecule. Nevertheless, the enzyme will denature and go less efficient the rate of reaction when the conditions get utmost change ( Campbell 2008 ).
Enzymes Enzymes are biological catalysts. A catalyst is defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanentchange. Enzymes do precisely this in living things. Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage.
Enzymes are found at work in almost all places in the body of any organism, whether plant, animal or bacteria. They are catalysts for many biological processes such as respiration, photosynthesis and the synthesis of proteins.
Enzymes are large proteins that are responsible for catalysing thousands of metabolic processes that sustain life. Enzymes work similarly to those catalysts used in industry by lowering activation energy and therefore dramatically speeding up the rate of a reaction, however, these biological catalysts are highly selective to their substrate.
Enzyme Lab. 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.
