3
Q
What is direct communication
A
gap junctions allow direct communication between adjacent cell
4
Q
What can pass through direct communication
A
small molecules and ions

What is indirect communication
A
through chemical messengers, a ligand is a molecule that reversibly binds to receptor proteins, which can initiate a cellular response
6
Q
What is unique about a ligand
A
It can be carried far away from the original cell and interact with a receptor on another cell
