Based on the provided text and Figure 40.15, which conclusion can be drawn regarding brown fat in human adults?

  • A: Brown fat is primarily located around the abdomen and is responsible for ATP synthesis.
  • B: Increased brown fat activity in adults is typically a response to prolonged exposure to warm environments.
  • C: Brown fat is metabolically active and can increase in amount in adults exposed to a cool environment.
  • D: The characteristic color of brown fat is due to a high concentration of ATP-producing enzymes.

Explanation

The text states that brown fat has been detected in human adults Figure 40.15 and that the amount has been found to vary, with individuals exposed to a cool environment for a month having increased amounts. The figure caption also confirms it shows 'metabolically active brown fat deposits'. This supports that brown fat is metabolically active and can increase in adults exposed to cool conditions.
