The transfer of nitrogen from the muscle to the liver occurs as a result of the action of Alanine. Alanine is important in the breakdown of glucose. The excretion of toxic substances is also a result of the action of Alanine. These substances are excreted from the muscle tissue post-exercise (Michael, 2011).
The liver accumulates alanine. After this accumulation is complete, a reverse of transamination takes place in the muscle. This occurs with the subsequent release of urea. The glucose-alanine cycle involves the amino acids breakdown also. This cycle involves the transfer of alanine from muscle to liver. Glucose is then transported back from the liver to the muscle. This cycle is very important to the muscle. Nitrogen waste is eliminated in the cycle and the energy reserves replenished. Production of Alanine in the body takes place via two pathways.
