I am in high school biology. I hope you guys can answer this. What process 
breaks apart the chemical bonds in glucose to release energy? Where in the 
cell does this aforementioned process occur if oxygen is not available? If 
oxygen is availiable?..... and i have one more question... How do producers 
use cell structures to provideenergy to other living things?   Email me back
