The point of the Krebs Cycle is to...

• Produce high amounts of ATP using a proton gradient

• Move high energy electrons through series of proteins to eventually bind with O₂, creating water and protons

• Break down pyruvate to produce electron carrier molecules, FADH₂ and NADH, as well as CO₂ and ATP as byproducts

• Use ATP and NADPH to produce 6 carbon sugars
