<ul>
	<li>All organisms that do photosynthesis rely on carbon dioxide (CO2).</li>
	<li>Carbon fixation? It&#39;s like the bodyguard that stops CO2 from leaving the photosynthesizing party.</li>
	<li>Star of the show? Rubisco! This enzyme turns CO2 into a fancier compound.</li>
</ul>

<ul>
	<li>🌍 Real-world example: Imagine CO2 is like the pop singer everyone wants at their party. It&#39;s in the atmosphere and enters cells when needed. But, it can also make a quick exit!</li>
	<li>CO2 moves easily: dissolves in water ➡️ passes through cell walls and membranes ➡️ enters the cell.</li>
</ul>

<ul>
	<li>Why&#39;s it called &quot;fixation&quot;? Because it stops CO2 from leaving the cell. Think of it as a VIP tag that ensures CO2 stays in the party.</li>
	<li>Main event: CO2 turns into a complex compound. This isn&#39;t just any reaction &ndash; it&#39;s like the &quot;Oscar-winning movie&quot; of all chemical reactions in organisms.</li>
</ul>

<ul>
	<li>Happens in the stroma (like the dance floor of our cell party). The stroma is the liquid that surrounds thylakoids in the chloroplast.</li>
	<li>End Product: A trendy three-carbon dance move named glycerate 3-phosphate.</li>
</ul>

<ul>
	<li>Plot twist: CO2 doesn&#39;t partner up with a two-carbon molecule to form glycerate 3-phosphate.</li>
	<li>Instead, it pairs with a five-carbon superstar named ribulose bisphosphate (RuBP) and produces not one, but two glycerate 3-phosphates!</li>
</ul>

<ul>
	<li>DJ Rubisco&#39;s full name? Ribulose-1,5-bisphosphate carboxylase-oxygenase. But, &quot;Rubisco&quot; sounds way cooler, right?</li>
	<li>This DJ makes the magic happen by turning RuBP and CO2 into our dance move, glycerate 3-phosphate.</li>
</ul>

<ul>
	<li>Most DJs (enzymes) play thousands of tracks (convert molecules) per second. But, Rubisco? Only about three CO2 tracks.</li>
	<li>Real-world example: Rubisco is like a vintage record player - classy and iconic, but not the fastest.</li>
	<li>BUT Rubisco has lots of fans (high concentrations) in the stroma to make up for its pace.</li>
	<li>Fun Fact: Rubisco might be the world&#39;s most abundant enzyme. Imagine it&#39;s like the Beatles of enzymes &ndash; everywhere and super influential!</li>
</ul>

✨ Did You Know? 
The total weight of Rubisco on Earth? A whopping 0.7Gt (700 billion kilograms) &ndash; that&#39;s like 100 million elephants! 🐘
