Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced

Exercise 2: Skeletal Muscle Physiology: Activity 2: The Effect of Stimulus Voltage on Skeletal Muscle Contraction Lab Report Pre-lab Quiz 1. Skeletal muscle fibers are innervated (stimulated) by c. motor neurons. 2. A single action potential propagating down a motor axon results in d. a single action potential and a single contractile event in the muscle fibers it innervates. 3. In resting skeletal muscle‚ calcium is stored in c. the sarcoplasmic reticulum. 4. During the latent period

Introduction/ Purpose: Stoichiometry is the study of the quantitative‚ or measurable‚ relationships that exist in chemical formulas and also chemical reactions. The calculations of a stoichiometry problem depend upon balanced chemical equations. The coefficients of the balanced equations indicate the molar ratio of the reactants and products taking part in the reaction. There are three major categories of stoichiometry problems such as mass-mass‚ mass-volume‚ and volume-volume. Convert to desired limit Molar

as catalysts to regulate metabolism by selectively speeding up chemical reactions in the cell without being consumed during the process. During the catalytic action‚ the enzyme binds to the substrate – the reactant enzyme acts on – and forms an enzyme-substrate complex to convert the substrate into the product. Each type of enzyme combines with its specific substrate‚ which is recognized by the shape. In the enzymatic reaction‚ the initial rate of activity is constant regardless of concentration because
