試題詳解

34. Which statement best describes how endosomes determine whether internalized receptors are recycled or degraded?
(A) Receptors destined for degradation are selectively packaged into intraluminal vesicles within multivesicular bodies.
(B) Recycling receptors are preferentially sorted in late endosomes after acidification.
(C) All internalized receptors transiently enter intraluminal vesicles before recycling.
(D) Ubiquitination directs receptors to recycling endosomes rather than lysosomes.
(E) ESCRT-mediated sorting occurs only after fusion with lysosomes.
