Production of glucose from the metabolism of amino acids, lactate and glycerol in the liver is known as ______.

Gluconeogenesis is the metabolic pathway of producing glucose from non-carbohydrate substrates like amino acids (from protein breakdown), lactate (from anaerobic glycolysis), and glycerol (from fat breakdown). Glycogenolysis is glycogen breakdown, glycogenesis is glycogen synthesis, so the correct answer is gluconeogenesis.
