  • Rate Of Reaction Hydrogen Bonding
    2,165 words
    RESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

  • Problems And Treatment Of Peptic Ulcer Disease
    1,624 words
    Peptic ulcers are open sores or raw areas in the lining of the stomach (gastric ulcer) or upper part of the small intestine (duodenal ulcer). They result when the bacterium, Helicobacter pylori attaches itself to the lining of the stomach. Another cause of peptic ulcers are nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen. The bacteria or NSAIDs weaken the protective mucus coating of the stomach and small intestines. This process allows acid to get through to the sensitive lining...

  • Bunsen Burner Hydrochloric Acid
    762 words
    The Problem: I am going to find out how temperature can affect the rate of reaction. Background information: Factors that change the rates of reactions are: ? Temperature? an increase in temperature will make the reaction occur faster. This happens because the particles of that substance move faster when it is heated. Because the particles move faster, they would collide more, making the reaction rate faster. ? Concentration? the increase in concentration, the greater and faster the reaction. Th...
