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.
