What is Photosynthesis?

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy (usually from the sun) into chemical energy stored in glucose. This fundamental biological process is essential for life on Earth as it produces oxygen and serves as the base of most food chains.

The overall equation for photosynthesis is: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

Plant Growth

Photosynthesis provides the energy and organic compounds necessary for plant growth, development, and reproduction.

Biomass Forests Food Production
  • Glucose synthesis for cellular respiration and structural components
  • Starch storage in roots, stems, and seeds
  • Cellulose production for cell wall formation
  • Lipid and protein synthesis from photosynthetic intermediates
Atmospheric Composition

Photosynthesis maintains Earth's atmospheric oxygen levels and removes carbon dioxide, playing a crucial role in climate regulation.

Climate Global Balance Carbon Cycle
  • Oxygen production for aerobic organisms
  • Carbon dioxide removal from atmosphere
  • Formation of fossil fuels over geological time
  • Influence on global temperature regulation

Photosynthesis Process Steps

Understand the detailed mechanisms of photosynthesis

Light-Dependent Reactions

Occurring in the thylakoid membranes, these reactions convert light energy into chemical energy (ATP and NADPH).

Photolysis Electron Transport ATP Synthesis
  • Photosystem II absorbs light and splits water molecules
  • Electrons travel through the electron transport chain
  • Photosystem I re-energizes electrons with additional light
  • ATP is synthesized via chemiosmosis
  • NADPH is formed from NADP⁺

Calvin Cycle (Light-Independent Reactions)

Taking place in the stroma, this cycle uses ATP and NADPH to convert CO₂ into glucose through carbon fixation.

Carbon Fixation Reduction Regeneration
  • RuBisCO catalyzes the fixation of CO₂ to RuBP
  • 3-PGA molecules are reduced to G3P using ATP and NADPH
  • Some G3P molecules form glucose and other carbohydrates
  • RuBP is regenerated to continue the cycle
