Detailed explanation-1: -Cell signalling takes place in the following three stages: Binding of the signal molecule to the receptor. Signal transduction, where the chemical signals activate the enzymes. Finally, the response is observed.
Detailed explanation-2: -Forms of signaling There are four basic categories of chemical signaling found in multicellular organisms: paracrine signaling, autocrine signaling, endocrine signaling, and signaling by direct contact.
Detailed explanation-3: -Connection for AP® Courses. The initiation of a signaling pathway results in a cellular response to changes in the external environment. This response can take many different forms, including protein synthesis, a change in cell metabolism, cell division and growth, or even cell death.
