<ul>
	<li>Think of energy conversion as you would of trying to stuff all your clothes into a suitcase. No matter how hard you try, you always end up with some socks or a T-shirt left out. Similarly, energy conversion isn&#39;t 100% efficient.</li>
	<li>In metabolic reactions
	<ul>
		<li>Reactants (ingredients) have more energy than the products (results).</li>
		<li>The extra energy? It turns into heat.</li>
	</ul>
	</li>
</ul>

<ul>
	<li>Birds and mammals are like living heaters! They use heat from metabolism to stay warmer than their surroundings.</li>
	<li>Real-world example: Think of the last time you felt super warm after running. That&#39;s your body&#39;s metabolism producing more heat than usual.</li>
</ul>

<ul>
	<li>Sometimes our bodies work a bit too hard and produce extra heat. Think of it like a car engine overheating.</li>
	<li>When we exercise, we sweat. Why? It&#39;s our body&#39;s air-conditioner. The sweat evaporates, cooling us down.</li>
</ul>

In icy cold conditions, emperor penguins are pros at teamwork. They huddle in groups, sharing their metabolic heat with each other. Imagine sharing a blanket with friends on a cold day &ndash; same concept!

<ul>
	<li>Birds and mammals have a sneaky trick: they can increase their metabolic rate to produce more heat.</li>
	<li>Humans, for example, shiver when they&#39;re cold. Ever wondered why? It&#39;s not just a random reaction. Shivering produces heat to warm up our body&#39;s core. It&#39;s like our body&rsquo;s natural heater turning on!</li>
</ul>

<ul>
	<li>Not all fats are the same! Many mammals have special &quot;brown fat&quot; tissue.</li>
	<li>What makes it unique? Cells in this tissue are packed with mitochondria (the cell&#39;s energy factories).</li>
	<li>The real magic: these mitochondria perform &ldquo;uncoupled respiration&rdquo;. This means they burn substances to generate heat WITHOUT making ATP (the energy currency of cells).</li>
	<li>Imagine it like a stove burning wood for warmth but not cooking anything. That&#39;s brown fat in action!</li>
</ul>

Quick Recap: Metabolic reactions generate heat. Animals, like birds and mammals, utilize this heat to maintain body temperature. When there&#39;s excess heat, mechanisms like sweating help. In cold conditions, animals have different tricks, like penguins huddling or humans shivering, to stay warm.
