Enzymes: Enzymes need energy to start reactions.Enzymes act as catalysts to help speed up chemical reactions. The active site is the space in the enzyme that the substrate binds to. The competitive inhibitor tries to enter the active site. The noncompetitive inhibitor doesn't compete with the active site. The reactants make the product.The products come off the substrates. Enzymes need to have equilibrium and optimal conditions because if not, the enzyme can denature and won't be able to perform its function. Enzymes work best at optimal conditions. Feedback inhibition helps regulate enzyme conditions. Coenzymes work with other enzymes.
Proteins: Proteins are made up of amino acids. There are 4 different levels of a protein structure. The primary structure is the 1st level, secondary is the 2nd level, tertiary is the 3rd level and quaternary is the 4th level. A peptide bond holds the primary structure together. Hydrogen bonds hold other protein structures together. Proteins can be denatured. If a protein is denatured the shape is changed so the protein can't do what it needs to (Form fits function).
