Exam 25 Flashcards
Intrinsic factor is produced in the
stomach
Carbohydrates absorbed from the intestinal tract may be used immediately, resulting in the production of pyruvate/lactate. The pyruvate is eventually converted back to glucose in the cori cycle of the liver. This process is known as
gluconeogenesis
