Question

Quizplus · Accepted Answer

Glucose is the preferred source of energy for the brain cells as it can cross the blood-brain barrier and is efficiently metabolized by the brain cells to produce ATP, the primary energy currency of cells. While the brain can also use ketone bodies and fatty acids for energy during periods of fasting or starvation, prolonged use of these alternative sources may lead to cognitive impairment and other neurological complications. Protein and amino acids are not efficient sources of energy for the brain cells and are primarily used for building and repairing the body tissues.
