Summary Introduction
To review:
The structure of phosphoenolpyruvate (PEP), and give a reason as to why it has a high transfer potential of phosphoryl group.
Introduction:
PEPis the product of the glycolysis process in which glucose gets converted into pyruvate. PEP has high phosphoryl group. It donates its phosphate group to adenosine diphosphate (ADP) to produce two molecules of ATP (adenosine triphosphate) and itself gets converted to pyruvate.

QUESTION 26
During gluconeogenesis, whereby liver cells convert pyruvate to glucose, Fructose-6-phosphate (F6P) is converted to Glucose-6-phosphate (G6P). If the standard equilibrium concentrations are: [F6P] = 0.52 M and [G6P] = 1.48 M, then Keq’ is ______ and the reaction is ________.
Fructose-6-P ó Glucose-6-P
> 1; exergonic
> 1; endergonic
< 1; exergonic
< 1; endergonic
True or False.
The Krebs cycle is considered to be an anabolic pathway because some of the reactions are considered reversible.
What would be the fate of oxaloacetate if there were sufficient fluoroacetate present?
