Problem 11: Gap Junctions

Direct cellular connections such as gap junctions in animal cells and plasmodesmata in plant cells permit:

A.	adjacent cells to adhere strongly to each other.
B.	second messengers produced in one cell to rapidly diffuse into and stimulate events in surrounding cells.
C.	adjacent cells to form a water-tight barrier between their membranes.
D.	protein kinases to flow between cells, coordinating cellular responses in a tissue.
E.	the rapid exchange of genetic information between adjacent cells.
