Question

What type of intermediate cytoskeletal filaments stretch across the interior of these cells and attach to the desmosome plaques located on opposite sides of the cells' interior?

Answer 1

Intermediate filaments known as keratins stretch across the interior of cells and attach to desmosome plaques, providing structural support and maintaining cell shape.

Step-by-step explanation:

The intermediate filaments that stretch across the interior of these cells and attach to the desmosome plaques located on opposite sides of the cells' interior are keratins. Intermediate filaments are a type of cytoskeletal filaments that provide structural support and maintain cell shape.

Keratin is a fibrous protein found in fur, hair, fingernails, and toenails. It forms bundles of rigid, insoluble extracellular proteins that align to form stable secondary structures.
