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. Drag each item to the appropriate bin.

Answer 1

Cell signaling involves three stages that are reception of signal molecules by the cell surface receptor, transduction of that signal molecules and response of the signal molecule.

Reception: In reception, the items that are involved are receptor molecules and cell surface receptors like G- protein-coupled receptors, receptor tyrosine kinase, enzyme-linked receptors.

Transduction: In transduction, the items involved are adenylyl cyclase, phosphorylation cascade, second messenger like cAMP, DAG and IP3.

Response: The response of cell signaling is the starting of molecular processes and the production of proteins.
