Krebs Cycle takes place in the:

• Cytoplasm
• Mitochondrial Matrix

• Ribsome
• InterMembrane Space of the Mitochondria

After the Krebs Cycle only a small portion of the energy of glucose has been converted to ATP. At this point the majority of usable energy is contained in

• NADH and FADH₂
• Carbon Dioxide 
• Acetyl-CoA
• Citrate
