Final answer:
Proteins can be broken down into amino acids for energy production when carbohydrates or lipids are insufficient.
Explanation:
Proteins can be broken down into individual amino acids which can then be used for energy production if carbohydrates or lipids are not available. About 10 percent of dietary proteins are catabolized each day to make cellular energy. The liver can break down amino acids for energy production, similar to how glucose is used to make ATP.
