Question

question 8
fat is used efficiently as fuel by the brain and nerves.
true
false

Explanation:

The brain and nerves primarily rely on glucose as their fuel source. While the brain can use ketone bodies (derived from fat breakdown) under certain conditions like starvation or very low - carbohydrate diets, it is not as efficient as using glucose. Fat (in the form of free fatty acids) cannot cross the blood - brain barrier easily to be used directly as fuel by neurons in the normal, well - fed state.

Answer:

False
