All organisms that do photosynthesis rely on carbon dioxide (CO2).
Carbon fixation? It's like the bodyguard that stops CO2 from leaving the photosynthesizing party.
Star of the show? Rubisco! This enzyme turns CO2 into a fancier compound.
Carbon dioxide (CO2) - the star ingredient
🌍 Real-world example: Imagine CO2 is like the pop singer everyone wants at their party. It's in the atmosphere and enters cells when needed. But, it can also make a quick exit!
CO2 moves easily: dissolves in water ➡️ passes through cell walls and membranes ➡️ enters the cell.
Carbon fixation - the bouncer of the party
Why's it called "fixation"? Because it stops CO2 from leaving the cell. Think of it as a VIP tag that ensures CO2 stays in the party.
Main event: CO2 turns into a complex compound. This isn't just any reaction – it's like the "Oscar-winning movie" of all chemical reactions in organisms.
The venue
Happens in the stroma (like the dance floor of our cell party). The stroma is the liquid that surrounds thylakoids in the chloroplast.
End Product: A trendy three-carbon dance move named glycerate 3-phosphate.
