Photosynthesis – Light & Calvin Cycle

Overview

  • Photosynthesis: converts light energy into chemical energy
  • Location: chloroplasts in plant cells
  • Equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Stages

  • Light reactions: happen in thylakoids and make ATP + NADPH
  • Calvin cycle: happens in the stroma and fixes CO₂ into glucose

Limiting factors

  • Light intensity: more light is faster, up to a point
  • Optimum temperature: roughly 25–35 °C
