Enzyme Notes Enzymes are ________________ made in the ____________________________, and their monomer is an ____________________________. Enzymes act as _________________ because they ______________________ chemical reactions by lowering _____________________________________________, the energy needed to __________________________. Enzymes are ________________________. All enzyme names end in the suffix - _________. Examples are __________________________________. ____________________ bind to enzymes at the ______________________ to begin a chemical reaction such as Hydrolysis or Dehydration Synthesis. There are two ways that substrates fit into an enzyme: 1. ______________________ - fit perfectly together 2. ______________________ - enzyme changes shape to fit the substrate There are four factors that affect the enzyme’s ability to speed up chemical reactions: ____________________ – decreases function by increasing or decreasing pH or temperature; Not at optimum performance 2. ______________________________– too many substrates, not enough enzymes 3. ______________________________ - too many enzymes, not enough substrates 4. ______________________________ - when enzymes are changed or reshaped by another protein (inhibitors) Two types of inhibitors (protein that prevents enzyme function): A. ____________________ – blocks substrate B. ____________________ – changes enzyme shape by binding elsewhere

Enzyme Questions What type of Biomolecule is an enzyme? In the picture on the right, label the Enzyme, the Substrate, the Enzyme-Substrate Complex, and the Products. Examine the Energy vs. Progress of reaction graph on the right. What does this graph tell you about the progress of chemical reactions with and without the presence of enzymes? Are all enzymes the same shape and size? Why or why not?
