Verified step by step guidance

Understand the question: The problem is asking about the body's preferred source of energy. This requires knowledge of metabolic pathways and energy production in biochemistry.

Recall the hierarchy of energy sources: The body prioritizes energy sources based on availability and efficiency. Glucose is the primary and most efficient energy source under normal conditions.

Explain why glucose is preferred: Glucose is metabolized through glycolysis, the citric acid cycle, and oxidative phosphorylation, yielding a high amount of ATP. It is also readily available in the bloodstream and stored as glycogen in the liver and muscles.

Compare with other options: Ketone bodies and fatty acids are used during prolonged fasting or low carbohydrate intake, while amino acids are primarily used for protein synthesis and only as a last resort for energy.

Conclude: Based on the metabolic pathways and energy efficiency, glucose is the body's preferred source of energy under normal physiological conditions.
