What can the liver use amino acids for? (select ALL that apply)
A. ATP
B. Gluconeogenesis
C. Ketogenesis
D. Glycogenolysis
E. Glycogensis
In only two amino acids are used
1: Gluconeogenesis :- in this process we use glucogenic amino acids which are Alanine,Arginine etc
2: Ketogenesis:- in this process we use ketogenic amino acids which are Leucine,Lysine

What is not true about gluconeogenesis?
Select one:
a. Gluconeogenesis shares seven steps of glycolysis
b. Three irreversible steps that differ between gluconeogenesis
and glycolysis are far from equilibrium.
c. Forming one glucose from pyruvate produces 4 ATP, 2 GTP and
2NADH
d. Acetyl-CoA can be converted into glucose in plants and
microbes, but not mammals.
e. Gluconeogenesis and glycolysis are reciprocally regulated to
prevent wasteful operation of both pathways at the same time.
D and B are wrong answers...
