So once again, we can have two of the same secondary messengers go on to different places in that cell and basically influence different processes and that could amplify the effects of that signal. Let's move on to four activation or in some cases inhibition of effectors. So what exactly is an effector? An effector is some type of molecule. It could be an enzyme, it could be a protein pump, it could be a membrane channel or it could be some type of transcription inducing molecule. So basically, these effectors are actually themselves responsible for carrying out some type of specific process that takes place inside the body.
