<human>:  Why is the AMPK protein called AMPK?
<bot>: AMPK stands for Adenosine Monophosphate-activated Protein Kinase. It is a protein that is activated by the energy-sensing molecule adenosine monophosphate. AMPK is a major cellular energy sensor, and is involved in many aspects of cellular metabolism. It helps cells respond to changes in energy status by switching on or off metabolic pathways that consume or produce energy.
