FAQ
Frequently Asked Questions
Primarily in the liver (about 90%), and to a lesser extent in the renal cortex (kidneys).
Lactate, glycerol, and the carbon skeletons of glucogenic amino acids (like alanine and glutamine).
It is hormonally regulated. Insulin suppresses it, while glucagon, cortisol, and epinephrine (adrenaline) stimulate it.
Broadly, yes. Glycolysis breaks down glucose to pyruvate, while gluconeogenesis builds glucose from pyruvate and other precursors. However, they are not simple reversals; several steps use different enzymes.
