Verified step by step guidance

Understand that the brain requires a constant and efficient energy source to function properly.

Recognize that glucose is a simple sugar and a primary energy source for many cells in the body, including brain cells.

Learn that glucose is metabolized through a process called glycolysis, which occurs in the cytoplasm of cells, producing ATP (adenosine triphosphate), the energy currency of the cell.

Acknowledge that while the brain can use other substrates like ketone bodies during prolonged fasting, glucose remains its preferred and primary energy source under normal conditions.

Conclude that the brain's reliance on glucose is due to its ability to cross the blood-brain barrier efficiently and provide a quick source of energy.
