Question

Cell signaling involves converting extracellular signals to specific responses inside the target cell. Different molecules are involved at each stage of the process. In this activity, you will sort items based on which stage they are involved in:
a) reception.
b) transduction.
c) response.

Answer 1

Answer:

Each cell can receive and respond to signals that they get from their surroundings. The three stages involved in transduction are reception, transduction, and response.

Reception: It involves receptor molecules and inducers. Receptors can be intracellular or extracellular. Receptors like G- protein-coupled receptor, receptor tyrosine kinase, and signaling molecules are the items that come under reception.

Transduction: In transduction, signals are transferred from outside of the cell to the inside of the cell. Secondary messengers are majorly involved in signal transduction like cAMP, cGMP, IP3, Ca2+, nitric oxide, etc.

Response: The response of cell signaling includes processes like protein synthesis, cell division, cell growth, etc.
