Solution
Protein can serve as an energy substrate if it is first converted to glucose.
Here's the step-by-step process:
-
When the body is low on energy, it can break down proteins to provide the necessary fuel. This process is called gluconeogenesis.
-
Gluconeogenesis occurs mainly in the liver and, to a lesser extent, in the kidneys.
-
In this process, amino acids (the building blocks of proteins) are converted into glucose.
-
This glucose can then be used as an energy source by the body, including the brain.
-
However, it's important to note that the body prefers to use carbohydrates and fats as its primary energy sources. Protein is typically used for energy only in situations of starvation
