Question

The shape of a cell and the mechanical properties of its plasma membrane are determined by a meshwork of fibrous proteins called what?

Choose one:
A. tight junction
B. glycocalyx
C. basal lamina
D. lamellipodium
E. cell cortex

Answer 1

The cell cortex is the meshwork of fibrous proteins that determines the shape of a cell and the mechanical properties of its plasma membrane.

Step-by-step explanation:

The shape of a cell and the mechanical properties of its plasma membrane are determined by a meshwork of fibrous proteins known as the cell cortex. The cell cortex is a thin layer of crosslinked actin filaments located just underneath the plasma membrane. This cortex is responsible for maintaining the shape of the cell and responding to mechanical deformations. The cell cortex is a dynamic layer of crosslinked actin filaments underneath the plasma membrane. It plays a key role in maintaining the cell's shape and providing mechanical support.
