An Overview of Cellular
RespirationChapter 7
He’s getting
chemical
energy from
his food!
Big DiagramDiagrams – 1 per team• Phase 1: Glycolysis – glucose
enters cell and is broken in half to make pyruvate
• Phase 2: Formation of Acetyl-CoA – pyruvate enters mitochondria and acetyl-CoA is formed
• Why does transferring electrons to oxygen release energy?When electrons move from glucose to oxygen, it is as though they were fallingThis “fall” of electrons releases energy during cellular respiration
Releaseof heatenergy
Glucose is a good fuel• It has a lot of hydrogens• Makes it a reservoir of
electrons• Those electrons want to go
to a lower energy state by moving toward the more electronegative oxygen
