Q1) Select all of the properties of adherins junctions

1)

use catenin proteins to link to cytosolic actin filaments

2)

use desmoplakin proteins to link with cytoslic intermediate filaments

3)

used for signaling extracellular stimuli into the cytosol

4)

link two cells together

Q 2 ) While most immunoglobulins (Ig\'s) are associated with the immune system, some are important for ___.

1)

mitosis

2)

exocytosis

3)

endocytosis

4)

meiosis

5)

cell-to-cell adhesion

Solution

Please find the answers below:

Part 1: All choices are correct (the cellular extensions and adherin jucntion can vary in form and name in different cell types but they perform the function of joining two cell by making intercellular junctions, making cellular/cytoplasmic extensions, joining of intercalated discs of the cardiac muscles and help in extracellular signalling via transfer of signalling molecules. Thus, the cellular communication is highly dependent upon these junctions).

Part 2: Choice 5 (The superclass of immunoglobulins also help in cell to cell adhesion by representing some receptors over the cell surface which act as ligand for other sturcutres on the cells and help in binding together of different cells. These structures are similar to cluster of differentiations and hence help in intercellular communication. )
