what would happen to the flow of carbon in central metabolism if alpha-ketoglutarate was being removed to make the amino acid glutamate?
Homework Answers
The flow of carbon would reduce if the alpha ketogluterate in the cell was made into the amino acid glutamate. Since alpha ketogluterate is a critical part of the TCA cycle and the TCA cycle is a vital part of respiration, the flow of carbon and energy would reduce.
The TCA cycle would not go on in the absence of alpha ketogluterate. anaplerotic reactions will also not occur in the absence of alpha ketogluterate.

alpha-Ketoglutarate plays a central role in the biosynthesis of several amino acids. Write a sequence of enzymatic reactions that could results in the NET synthesis of alpha-ketoglutarate from pyruvate. You may use other cofactors as required (e.g. NADH, ATP). There is no need to show structures, but indicate the name of each intermediate, the name of the enzyme, and balance each reaction for cosubstrates and cofactors. Each of the carbons in your alpha-ketoglutarate product must have originated from pyruvate.

Question 6 2 pts Some amino acids can supply the carbon required for gluconeogenesis by undergoing a reaction catalyzed by an aminotransferase, an enzyme that interconverts amino acids and -keto acids. Aspartate aminotransferase catalyzes the reaction shown below. aspartate + a-ketoglutarate - oxalacetate + glutamate A biochemist studying metabolism feeds 4-[14C]-aspartate (asparatate that has 14C, the radioactive isotope of carbon, at the sidechain carboxylate) to his rats. After sacrificing the rats he is unable to find any +4C in glucose....
