The large and rapid rise of luteinizing hormone (LH) in the bloodstream triggers __________.
A
the production of melatonin in the pineal gland
B
the initiation of DNA replication in somatic cells
C
the release of insulin from the pancreas
D
ovulation in females
검증된 단계별 안내1
Understand the role of luteinizing hormone (LH): LH is a hormone produced by the anterior pituitary gland and plays a critical role in regulating reproductive processes in both males and females.
Focus on the context of the question: The problem specifically mentions the 'large and rapid rise of LH in the bloodstream,' which is a key event in the female reproductive cycle.
Learn about ovulation: Ovulation is the process where a mature egg is released from the ovary, making it available for fertilization. This event is triggered by the LH surge, which occurs midway through the menstrual cycle.
Eliminate incorrect options: The production of melatonin in the pineal gland, initiation of DNA replication in somatic cells, and release of insulin from the pancreas are unrelated to the function of LH. These processes are regulated by other hormones or mechanisms.
Conclude that the correct answer is ovulation in females: The LH surge is directly responsible for triggering ovulation, which is a key event in the female reproductive cycle.
