Final answer:
Yes, steroid hormones can be stored in the endocrine cell that produces them.
Step-by-step explanation:
Steroid hormones, such as estrogen, can be stored in the endocrine cell that produces them. Once synthesized, steroid hormones are secreted into the bloodstream, where they bind to transport proteins to keep them soluble. At the target cell, the hormones are released from the carrier protein and diffuse across the plasma membrane. They then bind to intracellular receptors located in the cytoplasm or nucleus of the target cell. The hormone-receptor complex acts as a transcription factor, influencing the expression of specific genes.
