Question

Quizplus · Accepted Answer

Lipophilic hormones such as steroids and thyroid hormone bind with high affinity to receptors located inside their target cells, where they form hormone-receptor complexes that subsequently regulate gene transcription directly or indirectly. As a result, they do not require second messenger systems to transmit signals into target cells.
