Enzymes

Enzymes How does an enzyme-substrate-complex resemble a lock and key? Label the parts! Enzyme, Substrate, Active site, Product Substrate Enzyme Active Site Product Product Vocabulary Enzyme Catalyst that speeds up chemical reactions Catalyst A substance that speeds up a chemical reaction Optimum Temperature or pH at which the enzyme works best Denature When the active site of an enzyme changes so that the substrate no longer fits. Enzymes, Substrates, Products Complete the chart my filling in the enzyme for each substrate Starch Amylase Maltose Lipids Lipase Glycerol Fatty Acid Maltose Maltase Glucose Proteins Protease Amino Acids Sucrose Sucrase Glucose Fructose Activation Energy The red line represented the chemical reaction without the enzyme, and the black line represents the activation energy with the enzyme. In what way does the addition of the enzyme effect the chemical reaction? Enzyme A Enzyme B This graph shows that -- Enzyme A is less sensitive to pH than Enzyme B More enzymes are present at a higher pH pH effects the activity rate of enzymes Enzyme A is less effective at a lower pH than Enzyme B
