Why Does The Peptide Hormone Need To Use A Second-messenger? Two interdependent theses are proposed for the peptide hormone: that incoming signal transduction requires coupling to a G protein in a second-messenger pathway, and that second-messenger redundancy assures checks and balances in cell regulation. Why do some hormones need to trigger a second-messenger within the
What Is The Action Of A Hormone? A hormone is a chemical messenger that enables communication between cells. Hormones are secreted by the glands of the endocrine system and they serve to maintain homeostasis and to regulate numerous other systems and processes, including reproduction and development. What is the process of hormone action? Hormones activate
What Is The Role Of Second Messenger In Hormone Action? Binding of hormone to receptor initiates a series of events which leads to generation of so-called second messengers within the cell (the hormone is the first messenger). The second messengers then trigger a series of molecular interactions that alter the physiologic state of the cell.
