Question: The nematode cuticle is made up of……
Options:
Chitin
Structural proteins
Lipid
All of these
✅Explanation:
While the nematode cuticle is a complex structure containing various components, its primary building blocks are indeed structural proteins. The most abundant of these is collagen, a fibrous protein known for its strength and flexibility. Other structural proteins found in the cuticle include cuticlin and various glycoproteins.
Strength and Resilience: Collagen fibers create a sturdy framework that protects the nematode from mechanical damage and environmental stress.
Flexibility: The arrangement of proteins allows the cuticle to bend and flex, enabling the nematode's movement.
Permeability Barrier: Specific proteins and their arrangement contribute to the cuticle's ability to regulate the passage of water, gases, and other molecules.
