Episode notes
INSIGHT

Photosynthesis Powers Life

  • Photosynthesis converts light energy into chemical energy essential for life on Earth.
  • ATP and NADPH produced in light-dependent reactions drive energy processes in plants.
INSIGHT

Calvin Cycle and Rubisco's Role

  • The Calvin cycle fixes atmospheric CO2 onto RUBP to form sugars in plants.
  • Rubisco enzyme plays a crucial, though imperfect, role in carbon fixation.
INSIGHT

Rubisco's Dual Function Challenges

  • Rubisco is slow and can mistakenly use oxygen instead of CO2, causing wasteful photorespiration.
  • Photorespiration consumes energy and reduces photosynthesis efficiency.
