Cellular energy processes in plants and cells involve complex mechanisms of thylakoid light dependent reactions in chloroplasts and cellular respiration in mitochondria.
- The process begins with photosynthesis in chloroplasts, where light energy is captured and converted into chemical energy through electron transport chain reactions
- The Calvin cycle occurs in the stroma, where carbon dioxide is fixed into glucose through carbon fixation
- Cellular respiration involves multiple stages including glycolysis, the link reaction, Krebs cycle, and oxidative phosphorylation to generate ATP
- These processes are interconnected through electron carriers and energy molecules like ATP and NADPH
- The efficiency of these processes depends on environmental conditions like light availability and carbon dioxide concentration
