4. Maintenance of

internal

environment.

5. Production,

utilization and

storage of energy.http://www.sportsnutritionist.seotogrow.in/

WHAT IS A HORMONE RECEPTOR???????

A hormone receptor is a molecule that can bind to

a specific hormone. Receptors for peptide

hormones tend to be found on the plasma

membrane of cells, whereas receptors for lipid-

soluble hormones are usually found within the

cytoplasm. Upon hormone binding, the receptor

can initiate multiple signaling pathways which

ultimately lead to changes in the behavior of the

target cells.
