Question #46693
The Question
In an experiment, a male Periplaneta americana is exposed to a metabolic stressor that severely depletes cellular ATP. To maintain survival, the insect's physiology prioritizes the remaining ATP for the active transport of potassium urate into the Malpighian tubules. Consequently, energy is diverted away from the accessory reproductive glands. Which of the following represents the most likely reproductive outcome of this metabolic trade-off?
Options
- A.
The testes fail to undergo meiosis, resulting in the absence of spermatozoa in the seminal vesicles.
- B.
The mushroom gland fails to adequately synthesize the inner layers of the spermatophore, preventing successful sperm transfer to the female's spermatheca.
- C.
The phallic (conglobate) gland ceases to secrete nourishment for the sperm, leading to sperm death before copulation.
- D.
The male's spermatheca loses its ability to store mature sperm, rendering copulation ineffective.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: This question tests the functional integration of insect physiology and resource allocation.
The primary trap relies on anatomical misattribution—students frequently confuse male and female structures (e.g., assuming males have a spermatheca instead of seminal vesicles) or misunderstand the specific roles of the mushroom and phallic glands in spermatophore formation.
