<prompt> Regarding brown adipose tissue false isHigh ATP synthase activityHigh vascularityReduced or absent in the obeseHigh content of mitochondria  <response>: A High ATP synthase activity THERMOGENIN called uncoupling protein by its discoverers and now known as uncoupling protein 1, or UCP1 is an uncoupling protein found in the mitochondria of brown adipose tissue BAT. A mitochondrial uncoupling protein UCP-1 in BAT dissipates the hydrogen ion gradient in the oxidative respiration chain and releases energy as heat. The metabolic activity of BAT is increased by a central action of leptin, acting through the sympathetic nervous system that heavily innervates this tissue.
