Which of the following correctly describes the role of protein in the formation of energy? A) Proteins provide the building blocks for enzymes, hormones, and other essential biological molecules, but do not directly contribute to energy production. B) Proteins are the primary energy source for the body, providing the highest amount of calories per gram. C) Proteins are primarily used for tissue repair and growth and do not play a significant role in energy production. D) Proteins can be broken down into amino acids, which can be used to generate ATP through the citric acid cycle, but this process is less efficient than the breakdown of glucose or fats.
Understand the Problem
The question is asking to identify the correct statement regarding the role of proteins in energy formation. It presents multiple-choice options that highlight different functions of proteins related to energy production and metabolism.
Answer
Proteins can be broken down into amino acids, used to generate ATP through the citric acid cycle, although less efficiently than glucose or fats.
Proteins can be broken down into amino acids, which can be used to generate ATP through the citric acid cycle, but this process is less efficient than the breakdown of glucose or fats.
Answer for screen readers
Proteins can be broken down into amino acids, which can be used to generate ATP through the citric acid cycle, but this process is less efficient than the breakdown of glucose or fats.
More Information
Proteins are primarily used for tissue repair and growth rather than energy production. However, they can be used as a secondary energy source when necessary, although it's less efficient than using carbohydrates or fats.
Tips
A common mistake is assuming proteins are a primary energy source, similar to carbohydrates and fats. They provide energy only when those primary sources are not available.
