The Molecular Machine

Like Duolingo, but for The Molecular Machine. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

What you'll learn

Key ideas in The Molecular Machine

  • Hydrophobic side chains cluster in the protein interior to avoid water
  • Active sites are physical pockets shaped to fit specific substrates
  • The specific folding pattern creates unique binding surfaces for substrates
  • Enzymes lower activation energy by stabilizing the transition state
  • Changing a single link can cause the entire 'origami' structure to misfold
  • The 'induced fit' model involves the enzyme squeezing the substrate
  • Protein folding and hydrophobic core
  • Enzyme mechanisms
  • Heat breaks the weak hydrogen bonds that maintain a protein's 3D shape
  • Allosteric binding triggers a conformational change throughout the protein
  • Denaturation exposes hydrophobic cores, causing proteins to clump together
  • How the sequence of amino acids dictates the specific 3D structure and function
  • The shape shift at the distant site distorts the active site's 'lock'
  • Structural collapse is usually permanent because the folding path is lost
  • Regulation allows cells to toggle pathways based on molecule concentration
  • The physical mechanism of active sites in lowering activation energy
