Which type of cell junction allows for small ions and
molecules to pass from cell to cell?
a. adhering junctions
b. plasma membrain receptors
c. tight junctions
d. gap junctions
Homework Answers
Answer: Gap junctions
Explanation:
Gap junctions are also known as communicating junctions that are
composed of connexons. It allows molecules to pass directly from
one cell to another.
Tight junctions prevent molecules that pass through the
extracellular space and between adjacent cells.
Plasma membrane has channels that allow water, ions and small
molecules to pass from one cell to another.
Adherens junctions form adhesion belts that encircle the
cell.

A living cell extracts energy from organic "fuel" molecules in small, enzyme-catalyzed steps. This allows the process of energy extraction to be regulated. but less free energy is released from the molecules than would be released by burning them O and all of the energy is released as heat that can be used to do work in the cell O and some of the energy is stored in bonds of activated carriers O and more free energy is released from...
