The first event that happens after a signaling molecule binds to a receptor is:
A)the receptor transmits the message in a process called signal transduction.
B)there is a cellular response.
C)the receptor is activated.
D)the signal is quickly terminated to ensure a moderate response.

The first event that happens after a signaling molecule binds to a receptor is that the receptor becomes activated. It then undergoes a conformational change that allows it to transmit the message to the inside of the cell, where signal transduction pathways can take place and ultimately lead to a cellular response. The termination of the signal comes later in the process.
