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: reception, transduction, or response.

Answer 1

Answer:

Reception:

G protein-coupled receptor

Receptor Tyrosine Kinase

Signaling Molecule

Transduction:

Phosphorylation Cascade

Second Messenger

Adenylyl Cyclase

IP3, Ca2+, cAMP

Response:

Protein Synthesis

Explanation:

• Reception is situation whereby the signal molecule binds the receptor.
• Signal transduction, which is where the chemical signal results in a series of enzyme activations.
• The response, which is the resulting cellular responses.
