#Unit 6. System Physiology – Plant
  1. photorespiration is minimized
  2. The quantum yields for CO2 fixation remain constant at about 0.05 to 0.6 mole of CO2 per mole of photons

  3. The carbon-concentrating mechanism in C4 photosynthesis Accept all CO2 via photorespiration

  4. maximum quantum yield increases to about 0.09 mole of CO2 per mole of photons
