Pyruvate Oxidation (Transition Step)
pyruvate enters mitochondria and is converted into Acetyl-CoA before the Krebs/Citric Acid Cycle.
Acetyl-CoA
molecule that enters the Krebs/Citric Acid Cycle
Where does the Krebs/Citric Acid Cycle take place?
Mitochondrial matrix.
Krebs Cycle / Citric Acid Cycle
second stage of cellular respiration that completes the breakdown of glucose + makes CO₂, NADH, FADH₂, and small ATP.
NADH
electron carrier produced during glycolysis, transition step, and Krebs/Citric Acid Cycle.
FADH₂
electron carrier (similar to NADH) formed in Krebs/Citric Acid Cycle.
Waste product of the Krebs/Citric Acid Cycle?
Carbon dioxide (CO₂).
What is the main purpose of Krebs/Citric Acid Cycle?
to load NADH and FADH₂ with high-energy electrons to send to the ETC
How much ATP is made directly in Krebs Cycle?
only 2 ATP (small amount)
