In the Cori cycle
A) lactic acid is transported from the liver to muscle by the blood.
B) lactic acid is transported from the liver to the kidneys by the blood.
C) glycolysis takes place in muscle and gluconeogenesis in the liver.
D) glycolysis takes place in the liver and gluconeogenesis in muscle.

Question

Quizplus · Accepted Answer

The Cori cycle involves the conversion of lactic acid produced in muscle during anaerobic respiration into glucose in the liver via gluconeogenesis. Glycolysis takes place in muscle to produce lactic acid, which is then transported to the liver by the blood. In the liver, gluconeogenesis takes place to convert the lactic acid back to glucose, which is then transported back to the muscle for use in aerobic respiration. Therefore, choice C is correct. Options A and B are incorrect as they mention the liver transporting lactic acid to muscle or kidneys, which is not part of the Cori cycle. Option D is also incorrect as it suggests glycolysis takes place in the liver and gluconeogenesis in muscle, which is opposite to what occurs in the Cori cycle.
