ETC in respiration and photosynthesis
SLCC BIOL Videos・2 minutes read
Chemosis generates ATP in both chloroplasts and mitochondria through chemi-osmosis, with different processes involving electron transport chains and active transport of hydrogen ions to create energy from glucose and light, respectively. The final result is the production of ATP in both organelles, with different processes that convert light energy into chemical energy in photosynthesis and cellular respiration.
Insights
- Electrons from glucose in mitochondria are carried by NADH and FADH2 through protein complexes to create ATP, while in chloroplasts, light energy excites electrons to produce ATP and NADPH through active transport of hydrogen ions.
- Chemosis demonstrates the conversion of light energy into chemical energy during photosynthesis in chloroplasts and the utilization of electron transport chains to generate ATP in mitochondria, showcasing the dual mechanisms of energy production in cells.
