BCH210 RUNBACK EXAM QUESTIONS WITH ANSWERS GRADED A+ Lactate dehydrogenase - Answer-Pyruvate + NADH --> lactate + NAD+ Regenerates NAD+ for glycolysis when O2 is unavailable; in red blood cells, lactate is always produced since no mitochondria Cori cycle - Answer-1. Lactate is produced in the bloodstream by red blood cells 2. Liver picks up lactate; lactate dehydrogenase converts it back into pyruvate 3. Pyruvate is converted into oxaloacetate, where it either enters the CAC or GNG...
