In which receptor system, both receptor and ligand are recycled back to membrane
In cell biology, cellular compartmentalization and cell cycle dictates that SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. Therefore Transferrin receptor is correct as it aligns with membrane trafficking and cell cycle control, supported by mechanistic studies and conserved across related systems.
Ref: Alberts et al., Molecular Biology of the Cell, 6th Edition, Chapter 10, Membrane Structure and Transport, discusses SNARE proteins, vesicle trafficking, ER, Golgi, endosome membranes and selective transport providing compartmentalization foundation.
