Question:

What roles do steroid hormones play in the body, and how do they function?

Answer:

Steroid hormones, derived from cholesterol, play vital roles in various bodily functions including metabolism, inflammation, immune responses, and sexual characteristics. They function by penetrating cell membranes and binding to specific intracellular receptors. This binding influences gene expression, leading to long-term changes in cell function. Examples of steroid hormones are estrogen, which is crucial in reproductive and sexual development, and testosterone, which plays a key role in male sexual development and muscle growth.
