AMPK is not required for insulin-stimulated glucose uptake in skeletal muscle, as AMPK-deficient mouse models show normal insulin-stimulated glucose uptake.
Your body has multiple ways to manage glucose. Even if one pathway (like AMPK) is not functioning optimally, other mechanisms can still work. This highlights the importance of overall metabolic health rather than focusing on a single molecule.
GoodRefutesHIGH confidence
Basal and insulin-stimulated glucose uptake in isolated muscles is normal in AMPK α2 KO mice, further supporting that insulin resistance was caused by an external defect independent of skeletal muscle AMPK.
Why this rating
Based on multiple knockout mouse models.
