2. The Ala that comes from the muscle is returned to the muscle as
   1. pyruvate                      c. glucose
   2. glutamate                    d. a-ketoglutarate

3. Oxaloacetate enters the urea cycle as  
   1. citrulline                      c. glutamate
   2. aspartate                      d. fumarate

4. The oxidation of pyruvate to AcCoA uses similar cofactors as the oxidation of
   1. malate
   2. succinate
   3. a-ketoglutarate
   4. isocitrate

5. The enzyme that requires FAD as cofactor is
   1. a-ketoglutarate dehydrogenase complex
   2. isocitrate dehydrogenase
   3. malate dehydrogenase
   4. succinate dehydrogenase

Answer 1

produced by one cycle + And Number of electron of Kieb 1 Kreb cycle generate 3NADH I NADH give de I FADH2 give aé FADHQ Total 3x2 = 6 + 2 - se So option 6 correct as glucose 2) Alanine that comes from the muscle is returned to muscle option c correct to liver there converted to pyruvate Pyruvale through gluconeogenesis converted to glucok that glucose goes to muscle. Alanine goes 37 oxaloacetate enter the crea cycle as aspartate (b) 4) a ketoglutarate 5) Malate dehydrogenase
