What is the primary fuel source for the brain?

Question

Quizplus · Accepted Answer

The primary fuel source for the brain is glucose. The brain relies heavily on glucose for energy and cannot store large amounts of glucose. Therefore, it requires a constant supply of glucose from the blood. While fatty acids and amino acids can be used as alternative energy sources during periods of starvation, glucose is the preferred fuel source for the brain under normal conditions. Neurotransmitters and electrolytes are important for proper brain function, but they are not fuel sources.
