When muscle proteins are catabolized in skeletal muscle during a fast, what are the fates of the glucogenic amino acids and other amino acids? Glucogenic amino acids are converted to glucose in the muscle cells. Other amino acids are oxidized in mitochondria via the citric acid cycle. Glucogenic amino acids are converted to glucose in the liver. Other amino acids are oxidized in mitochondria via the citric acid cycle. Glucogenic amino acids are converted to glucose. Other amino acids are excreted in the urine. Glucogenic amino acids are stored in the brain. Other amino acids are stored in the liver. Glucogenic amino acids are sent to the brain to be converted to glucose. Other amino acids are oxidized in mitochondria via the citric acid cycle.
