Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The three stages of cell signalling are
A
paracrine, local, and synaptic
B
reception, transduction, and response
C
transcription, translation, and folding
D
alpha, beta, and gamma
Explanation: 

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: -Signals are classified into the following categories: Continuous Time and Discrete Time Signals. Deterministic and Non-deterministic Signals. Even and Odd Signals.

Detailed explanation-3: -The three stages of cell communication (reception, transduction, and response) and how changes couls alter cellular responses. How a receptor protein recognizes signal molecules and starts transduction.

Detailed explanation-4: -Response: It is the third stage of cell signaling where the transduced signal finally triggers a specific cellular response.
