Question #46740
The Question
During spermiogenesis, the formation of the acrosome is critically dependent on the coalescence of proacrosomal vesicles. If a targeted chemical inhibitor specifically disrupts the polarity of the Golgi apparatus in developing spermatids, which of the following reproductive events will be most directly and immediately compromised?
Options
- A.
Digestion of the corona radiata and zona pellucida by hyaluronidase and acrosin.
- B.
Completion of meiosis II in the secondary oocyte due to the lack of proximal centriole delivery.
- C.
Motility of the spermatozoa through the cervical mucus due to defective Nebenkern formation.
- D.
Formation of the syncytiotrophoblast and subsequent implantation of the blastocyst.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Linking cell biology (Golgi function) to human reproduction (spermiogenesis).
The primary trap is distinguishing the immediate biochemical failure (acrosomal reaction) from downstream systemic failures (implantation) and differentiating the origins of sperm organelles (Golgi vs.
Mitochondria vs.
Centrosome).
