Document Summary
Most of who we are made of extracellular matrix ligaments, tendons, etc. are built by cells. Humans are mostly protein, plants are mostly carbohydrates. Natural hierarchy: atomic > molecular > cellular > tissue > organ > organ system > The actual physical form determines what it can do. Cilia pushes mucus out of esophagus; smokers lose cilia so they have to mechanically push mucus out of their esophagus. Building blocks of our cells are made out of polymers. Polymers refer to some type of macromolecule; built out of repeating subatomic units (monomers) Proteins: monomer = amino acid, 20 different amino acids in humans, can make very important polymers from these amino acids. Macromolecules: grouped together off the monomer from which the macromolecule is built. Condensation water is lost and a bond between monomers is formed to make a polymer. Hydrolysis water is added and a bond between a polymer is broken. All of these reactions are done by enzymes.
