Lipids and carbs both rock as energy sources. Imagine them as fuel for our body's car! 🚗💨
They're both burned (oxidized) to release energy. Imagine your favorite carbohydrate (maybe it's pasta?) and your favorite lipid (like butter) acting as your body's little power stations!

Carbohydrates - They can party with or without oxygen! 🎉
- First Stage: Begins with sugars like glucose transforming in a process called glycolysis. This creates ATP (our energy currency) and doesn't need oxygen. So, think of glucose dancing without needing to breathe!
- But after this step, if glucose wants to keep the party going, it needs oxygen. It's like it wants to start a new dance in the Krebs cycle, but needs oxygen as its dance partner.
Lipids (fats and oils) - They NEED oxygen to show their moves. 🕺💨
- They start by breaking down into acetyl groups in our cell's powerhouse - the mitochondrion. Then they, too, dance into the Krebs cycle.
- Without oxygen, lipids are like fish out of water; they simply can't respire without it.
