The photosynthesis process and cellular respiration are fundamental biological processes that convert energy between different forms. The process involves two main stages - the Lichtabhängige Reaktion der Fotosynthese (light-dependent reaction) and Lichtunabhängige Reaktion Fotosynthese (light-independent reaction), occurring in chloroplasts. This complex system enables plants to convert light energy into chemical energy, producing glucose and oxygen while consuming carbon dioxide and water.
Key points:
- Photosynthesis occurs in chloroplasts through light-dependent and light-independent reactions
- The Calvin-Zyklus is crucial for carbon fixation in the light-independent phase
- Cellular respiration takes place in mitochondria through multiple stages
- The process generates ATP through various chemical pathways including glycolysis and the citric acid cycle
- The overall efficiency of these processes determines plant growth and energy production
