In this chapter's tools
Prediction scenarios 3
- Level 1 narrow a tube, predict flow
- Level 1 add solute to one side of a membrane, predict water movement
- Level 1 add acid to a buffered vs unbuffered solution
Graphs 3
- The pH scale is logarithmic
- Flow vs vessel radius (fourth-power curve)
- Enzyme activity vs temperature and pH
Calculators 1
- Flow and resistance (F = ΔP/R, halving the radius)
Comparison tables 4
- Ionic vs covalent vs hydrogen bonds
- Acid vs base vs buffer
- Carbohydrates vs lipids vs proteins vs nucleic acids
- Diffusion vs osmosis vs bulk flow
