Question 3

What happens during protein catabolism? How is this related to nitrogen balance?

[Expo]

Answer to Question 1

Ketosis is a high concentration of ketone bodies in body fluids. Ketone bodies are metabolites with the ketone group that form during starvation states. When glucose levels are low, the liver turns to fats and amino acids to provide energy. This produces much acetyl-CoA, which leads to production of ketone bodies. Because most ketone bodies are acidic, they lower the pH of body fluids, bringing on acidosis. If severe, the ketosis and acidosis can injure the CNS, heart, and other organs. In extreme cases, death can result.

Answer to Question 2

C

Answer to Question 3

Protein catabolism is the breakdown of proteins by cellular proteases and peptidases into constituent amino acids. These amino acids can be either reused for protein synthesis (anabolism) or broken down via deamination and used to make glucose or directly used in the citric acid cycle to make ATP. Deamination removes the nitrogen group from the amino acid, which is then excreted as urea. This results in a negative nitrogen balance.
