Question
Chapter 16, Problem 43P
Interpretation Introduction
Interpretation:
Removal of an amino group from alanine and aspartate can contribute to gluconeogenesis.
Concept introduction:
Gluconeogenesis is the process of conversion of lactic acid back into glucose. This process uses energy in the form of 6 NTP molecules, hence, it is endogenic in nature. This process is responsible for increasing the blood glucose level when glucose levels fall down in blood.

disease. As such, a frontline treatment for Type 2 diabetes is the drug metformin, which acts indirectly
to inhibit gluconeogenesis in the liver. You are a research biochemist who would like to develop new
drugs that act to directly inhibit gluconeogenesis. You have just gained access to a library of thousands
of small molecules of unknown activity, and you would like to identify lead compounds that have specific
inhibitory activity against steps in the gluconeogenesis pathway.
(a)
into PEP in order to screen for inhibitors of enzymes specific to gluconeogenesis. Which enzymes do
you need to purify, what cofactors and allosteric effectors do they require, and which reactants do you
need to add to reconstitute the reactions for the first bypass? Which intermediates and products are
generated?
Your first approach is to reconstitute the initial set of bypass reactions that convert pyruvate
(b)
vitro reconstitution?

Pernicious anemia. Purine biosynthesis is impaired by vitamin B12
B12 deficiency. Why? How might fatty acid and amino acid
metabolism also be affected bya vitamin B12B12 deficiency?
Accepting. Which of the following compounds readily accepts amino
groups from amino acids?
a. Glutamine
