1. Receptor activation 2. Signal transduction 3. Cellular response |
3 steps of communication |
|
|
Receptor activation |
Step of communication where the signal causes receptor to change shape and become active |
|
|
Signal transduction |
A step of communication where the receptor initiates a series of steps to take the signal inside the cell |
|
|
Cellular response |
Step of communication that is extremely varied, but appropriate for the signal (alter shape, production of a chemical, protein synthesis, metabolic rate, xcetera.) |
|
|
Types of local signaling |
Cytoplasmic communication contact - dependent , synaptic, paracrine , autocrine |
|
|
Type of long distance signalling |
Endocrine |
