The Role of Antioxidants in Exercise Induced Muscle Damage. Free Radicals Induce Muscle Damage and Inflammation Research evidence proves that free radicals play an important role in muscle damage and inflammation after strenuous exercise. Dietary antioxidants are able to assist in the protection against free radical damage and the prevention of cellular damage. Free radicals are formed when oxygen interacts with certain molecules forming atoms or groups that have an odd number of electrons

There are many reasons why enzymes have such a high specificity. The first variable is an enzyme’s primary structure. A primary structure is just a combination of amino acids. There are twenty different amino acids that the primary structure can be created from. Every enzyme has a different order that the acids are placed in and each one has a different number or amino acids. The slightest change in this structure can affect a protein’s conformation and function. The secondary structure is a regular

activity of enzymes.(www.biology.kenyon.edu) Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.(www.livescience.com) Enzymes speed up chemical reactions by providing an alternate reaction pathway and lowering activation energy. Enzymes are vital for life and serve a wide range of important functions in the body‚ such as aiding in digestion and metabolism. (Biology Lab Manual) Some enzymes help
Premium Enzyme Chemical reaction Catalysis
Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates

Most of life’s biological processes involve the use of protein catalyst called enzymes‚ that help speed up chemical reactions within the body without being denatured in the processes. Enzymes can be used continually by temporary binding to a specific substrate in the active site to convert the substrate into a product that the cell needs to perform a specific function. Without the use of catalyst enzymes‚ homeostasis wouldn’t be able to occur quickly enough which can result in many bodily functions
Premium Enzyme Chemical reaction Metabolism
Concentarion ENZYME LAB Introduction- Enzymes are proteins that speed up the rate of reactions in living things. In this lab‚ we will perform four experiments exploring the way enzymes work. PART A: pH SPECIFICITY Every enzyme has a specific pH at which it works best. In this section‚ you will determine which pH is best for the enzyme‚ catalase. Living tissues produce the enzyme catalase‚ which is able to break down hydrogen peroxide into oxygen gas and water. The reaction is
Free Enzyme Starch
Abstract Enzymes are biological catalysts that speed up the rate of chemical reactions by lowering the reactants’ activation energy. The goal of this lab was conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine
Premium Enzyme Starch Amylase
Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected
