Cells can communicate with one another via:

• chemical messengers

• hormones

• gap junctions

• all of these

The three stages of cell signalling are

• paracrine, local, and synaptic
• reception, transduction, and response
• transcription, translation, and folding
• alpha, beta, and gamma

cAMP and calcium are examples of 

• secondary messengers
• hormones
• ligands
• enzymes

A signal molecule that binds to a plasma-membrane protein is a

• ligand
• second messenger
• protein kinase
• receptor protein
