Describe, in detail, the two molecular processes in steroid and peptide action

Hormone - biologically active molecule that is released into circulation from site of synthesis and acts at a distant sitecan be either hydrophilic (polypeptide hormone) or lipophilic (steroid) - biogenic amines can be eitherbinds specific receptor - on cell surface (hydrophilic hormones) or inside cell (lipophilic hormones) lipophilic hormones bind carrier proteins to travel in circulation; hydrophilic hormones travel freelycis-acting elements - DNA segments in the promoter region which bind trans-acting elementstrans-acting elements - molecules that impact downstream gene transcription when they bind cis-acting elements
