Which process drives exoskeleton molting in larvae during incomplete metamorphosis when ecdysone pulses decrease?

💡 Explanation

When ecdysone decreases during cycles after larval stages, specialized enzyme secrection degrades the old cuticle because the inhibitory effect of ecdysone diminishes. Therefore, digestive enzyme reduction slows shedding the old exoskelton, rather than apoptosis, chitinase increase, or epidermal cell division which require completely different hormonal regulations.
