Hormones

Description

Hormones are Proteins that are produced in one part of the body (by an Endocrine Gland), passed into the bloodstream and carried to distant organs for use in biological processes.

 Hormones are transported around the body (often via specific binding Globulins) via Plasma within the Bloodstream.  When in close proximity to a cell, Hormones are released from their binding Globulins and readily "float" through Cell Membranes into the Cytoplasm of Cells, where, if they encounter an appropriate Receptor for the specific Hormone, they migrate into the Cell's Nucleus for biding with an accessible DNA segment (genome).  This results in the formation of a specific RNA by which the cellular effects of the Hormone are accomplished.  If the Hormone "floats" into a cell that lacks an appropriate Receptor for the Hormone, it "floats" on through and out of the Cell again.
