Answer #1

A,B and C are correct

  • First reaction is the conversion of pyruvate to oxaloacetate catalyzed by pyruvate caboxylase. This reaction occurs in mitochondrial matrix.
  • Second reaction is the conversio of oxaloacetate to phosphoenol pyruvate catalyzed by PEP carboxykinase
  • This conversion of pyruvate to PEP requires 1GTP and 1ATP
  • The conversion of glucose-6-phosphate to glucose catalyzed by glucose-6-phosphatase, which is present in the membrane of ER of liver and kidney cells but is absent in muscle and brain
  • For this reason gluconeogenesis is not carried out in mauscle and brain

1. Aspartate is metabolized to oxaloacetate, which we know via gluconeogenesis can be used to generate PEP. Assuming the PEP then proceeds to pyruvate and acetyl CoA and enters the citric acid cycle, how much ATP could be generated from the complete oxidation of Aspartate if we assume 1 NADH produces 3 ATP, 1 FADH2 produces 2 ATP, and GTP or ATP are equivalent (1GTP=1ATP). (Also ignore the “cost” of Nitrogen removal; don’t consider the urea cycle) 2. True or...
