Definition
The brain requires a continuous supply of energy and nutrients because its cells remain metabolically active even during sleep.
Formula / Key Relation
Brain cells have high energy requirements. The bloodstream supplies: glucose; oxygen; * other nutrients. Aerobic respiration provides energy needed for ion transport and cellular activity. Simplified respiration: `glucose + oxygen → carbon dioxide + water + energy`
