In this chapter's tools

Lab practical image sets 2

  • Parts of a generalized cell
  • Mitosis stages (OpenStax micrographs)

Prediction scenarios 3

  • Level 1 a red blood cell placed in a hypertonic solution
  • Level 2 the sodium–potassium pump is poisoned
  • Level 2 oxygen supply to a cell is cut off

Pathways 4

  • Protein synthesis: gene to secreted protein
  • The secretory pathway: ER to Golgi to exocytosis
  • Phases of mitosis
  • Stages of cellular respiration (overview)

Comparison tables 5

  • Passive vs active transport
  • Simple vs facilitated diffusion vs channels
  • Isotonic vs hypotonic vs hypertonic
  • Tight junction vs desmosome vs gap junction
  • Aerobic vs anaerobic metabolism
