Final answer:
The primary source of fuel for the brain is carbohydrates, specifically glucose. Consuming carbohydrates is important for proper brain function and overall biological processes.
Step-by-step explanation:
The primary source of fuel for the brain is carbohydrates. The brain mainly relies on glucose, a type of carbohydrate, to function. Glucose is obtained from the digestion and breakdown of carbohydrates in the body.
Carbohydrates are broken down into glucose, which provides the energy needed for cellular function and is converted into ATP, the energy currency of the cell.
It's important to consume carbohydrates as they are necessary for proper brain function and overall biological processes.
