The Cori cycle is a metabolic pathway that involves active muscles and the liver. In the liver, fatty acids react to form C O 2 and H 2 O, releasing A T P, and lactate uses the A T P to form glucose in a process called gluconeogenesis. The glucose moves to the muscles to form lactate, releasing A T P, a process called glycolysis. The lactate then moves from the muscles to the liver to complete the cycle. Complete the sentences about the Cori cycle. Muscles break down into , which undergoes glycolysis. The end product of glycolysis in active muscles is , which is transported in the blood. The liver uses energy from to drive . The produced in the liver is transported to the muscle in the bloodstream. Answer Bank
