Biology: The Logic of Life, a free science course on Tomo

Biology: The Logic of Life

Move beyond memorizing parts to understanding the systems that drive all living things. Explore how energy, information, and environment interact to create the complexity of the natural world.

Like Duolingo, but for Biology: The Logic of Life. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

21 levels across 3 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through The Living Machine, Information and Inheritance, and Systems in Balance. It assumes you already know the basics.

What you'll learn

Key ideas in Biology: The Logic of Life

  • ATP releases energy by dropping its third phosphate group to become ADP
  • Enzymes lower the activation energy needed to start a chemical reaction
  • The transfer of a phosphate group changes a protein's shape to do work
  • The active site physically strains bonds in the substrate to make them break
  • Cells regenerate ATP by adding a phosphate back to ADP using food energy
  • Catalysts speed up reactions without being consumed in the process
  • How ATP powers cellular work through energy transfer
  • The role of enzymes in overcoming activation energy
  • Substrates are modified by specific enzymes at every step of the chain
  • Intermediate molecules serve as the 'output' of one step and 'input' for the next
  • Metabolic pathways are often branched, diverting intermediates to different needs
  • High concentrations of a product signal the cell to stop further production
  • Allosteric regulation allows a product to flip an enzyme's 'off switch'
  • This mechanism prevents the wasteful accumulation of unneeded amino acids
  • The sequential nature of metabolic pathways
  • The mechanism of feedback inhibition in resource management
