Question

Which of the following statements about focal adhesions is true? They anchor cells to the substratum. They can be rapidly disassembled upon a changing environment. They may act as a type of sensory structure leading to cell growth. All of these answers are correct

Answer 1

All of these answers are correct.

Step-by-step explanation:

Focal adhesion may be defined as the junction by which the signals are transmitted between the interacting cell and the extracellular matrix. They contain the protein integrin.

The focal adhesion can be disassembled rapidly as the environment changes. They are important for the cell signalling as well as for the cell growth. They helps in the attachment and anchors the cells with its substratum. Hence, all the given options are correct.

Thus, the correct answer is option (4).
