Which metabolic sensor kinase becomes activated when cellular AMP/ADP levels are high, promoting catabolic pathways and inhibiting anabolic pathways?
Show answer and explanation
Correct answer: AMP-activated protein kinase (AMPK)
AMP-activated protein kinase (AMPK) senses low-energy states via increased AMP/ADP, and activates processes that generate ATP (like fatty-acid oxidation) while inhibiting energy-consuming anabolic processes, restoring energy balance.
