Homework Answers
Kerbs cycle or TCA cycle or Citric Acid Cycle is the second phase of aerobic respiration that comes after the proces of glycolysis which produces pyruvate and this pyruvate goes to a intermediate stage where it gets converted into acetyl CoA which when comes together with oxaloacetate to produce CO2, NADH, FADH2, and ATP or GTP.
FADH2 : Kerbs cycle
ATP : Kerbs cycle
CO2 : Kerbs cycle
Acetyl CoA :Intermediate step
Pyruvic acid : Glyciolysis
NADH : Kerbs cycle
Proton gradient : Electron transport chain

A fatty acid composed of 20 carbon atoms undergoes β‑oxidation. How many acetyl CoA, FADH2, and NADH does β‑oxidation of this fatty acid generate? (answer is 10 acetyl CoA, 9 FADH2, 9 NADH) Calculate the net ATP generated by the β‑oxidation of the 20‑carbon fatty acid. Assume that each FADH2 generates 1.5 ATP and each NADH generates 2.5 ATP. number of ATP molecules: ??????
