By bind with specific receptors, the hormones are able to regulate reproduction, development, energy metabolism, growth, and behavior. The reason why it is important that these functions be activated through hormones (a signaling molecule) is because there is an exact time that these functions need to happen. A caterpillar can't start changing into a butterfly if it hasn't finished its cacoon yet.
isn't this from the January 2008 regents?Two primary agents of cellular communication are hormones and chemicals made by nerve cells.
hormones and chemicals made by nerve cells...option 4
Cellular operations are altered by hormones, as the hormones that are produced by a body go together to either age a hormone quickly, or to stop the aging of the hormone altogether, essentially killing it.
Receptors are important because they play a key role in cell signaling. They allow communication between the cells to facilitate cellular processes.
