Question

Cell junctions that promote the coordinated activity of cells by physically binding them together into a cell community include all of the following except ________?

1) gap junctions
2) desmosomes
3) peroxisomes
4) tight junctions

Answer 1

Cell junctions that promote the coordinated activity of cells include tight junctions, gap junctions, and desmosomes.

Step-by-step explanation:

Cell junctions that promote the coordinated activity of cells by physically binding them together into a cell community include tight junctions, gap junctions, and desmosomes.

Tight junctions form watertight connections between adjacent animal cells, preventing the leakage of substances between the cells. Gap junctions allow for direct communication between cells by creating channels that allow the movement of ions and small molecules. Desmosomes are intercellular 'rivets' that create tight bonds between cells, giving tissues their strength.
