Feed-Fast Cycle
Q. Why does the liver produce ketone bodies during fast when it can just produce glucose via gluconeogenesis?
a
Ketone bodies spare glucose for the peripheral tissues.
b
Gluconeogenic substrates include amino acids from skeletal muscle; ketogenesis prevents the degradation of essential proteins.
c
Ketone bodies promote the degradation of muscle proteins, and therefore spare nutrients for the brain and red blood cells.
d
None of the above.
