Question

The specificity of signaling pathways does not include ___________

(a) Migration of signal proteins into membrane rafts

(b) Assembly of large multiprotein complexes

(c) Phosphorylation of target proteins at Ser, Thr/Tyr residues

(d) Flippase-catalyzed movement of phospholipids from the inner to the outer leaflet

The question was posed to me by my school teacher while I was bunking the class.

I'm obligated to ask this question of Multivalent Scaffold Proteins and Membrane Rafts topic in chapter Biosignalling of Biochemistry

Answer 1

Correct answer is (d) Flippase-catalyzed movement of phospholipids from the inner to the outer leaflet

To explain I would say: The specificity of signaling pathways does not include flippase-catalyzed movement of phospholipids from the inner to the outer leaflet.
