Connexons are proteins used in which of the following junctions?
A
Adherens junctions
B
Tight junctions
C
Gap junctions
D
Plasmodesmata
Verified step by step guidance1
Understand the function of connexons: Connexons are integral membrane proteins that form channels allowing the passage of ions and small molecules between adjacent cells.
Identify the type of junctions: There are several types of cell junctions, including adherens junctions, tight junctions, gap junctions, and plasmodesmata.
Recognize the role of gap junctions: Gap junctions are specialized intercellular connections that facilitate direct communication between cells through connexon channels.
Differentiate between junctions: Adherens junctions and tight junctions are involved in cell adhesion and creating barriers, respectively, while plasmodesmata are plant-specific channels.
Conclude that connexons are specifically associated with gap junctions, as they form the channels that enable communication between cells in this type of junction.
