Question

Quizplus · Accepted Answer

The glucose-alanine cycle functions in the exchange of carbon and nitrogen between the liver and muscle. In this cycle, the muscle releases alanine, which is converted into pyruvate in the liver. The pyruvate can then be used for gluconeogenesis, while the nitrogen is used to form urea and is excreted by the kidneys. The glucose produced in the liver can be used by the muscle for energy.
