- When your cells burn sugar fuel
from your meal (such a deal!),
there are three parts to the job
and you get some ATP.
- First you do glycolysis.
Split that sugar right in half,
and you make two ATPs:
store some energy.
- Second comes the Kreb’s cycle,
break it down to CO2
in your mitochondria,
and you make more ATP.
- Third, your mitochondria
transport those electrons.
Grab their energy to make
lots and lots of ATP.
- Then you dump those electrons
and some extra hydrogen.
Bond them onto oxygen
and you get some water.
- Forty total ATPs:
glycolysis uses two,
and eukaryotes use two more
so the total’s thirty-six.
