The exoskeleton of arthropoda is made of a tough protein called chitin, a long-chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals (found in hair, nails, hooves, claws, beaks, etc). Some arthropods, like crustaceans, further harden their exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed their entire exoskeleton in order to grow.
What else can I help you with?
Is chitin an enzyme?
No, it is a polysaccharide that makes up the exoskeletons of arthropods.
What polysaccharides is found in the shells of crustaceans?
Chitin, N-acetylgucosamine, makes up the exoskeletons of crustaceans.
What happens to an arthropod's exo skeleton as the arthropod grows up?
As the arthropod grows up, the exoskeleton sheds in order for the arthropod to grow inside of it.
How are lobsters and chitin related?
Lobsters are crustaceans, and chitin is the hard polysaccharide substance that makes up the outer shell (exoskeleton) of crustaceans. Chitin also makes up the exoskeletons of other arthropods (insects, etc.). It helps to strengthen the cell walls of fungi and the shells of mollusks as well.
What hard substance is a starfishe's exoskeleton made of?
Starfish actually have ENDOskeletons, not exoskeletons. They are made up of calcium carbonate compounds called ossicles.
How would taking in water or air before a new exoskeleton hardens help an arthropod?
Arthropod means "jointed legs," because arthropods are covered with a hard skin ("crab shells" are the hard skin of crabs) and they move by flexing joints along their hard skin. When they grow, they have to grow inside their hard skin. But, if the skin is too tight, there's no space! By taking in air or water when their shell is still soft, arthropods can "pump up" and make a nice roomy shell to grow in. When they fill that shell up, they crawl out of it, and then pump up the soft skin underneath. The pumped up soft skin hardens into hard skin, and the arthropod is ready to keep growing.
What is a cell wall composed of that is also found in the exoskeleton of insects?
Cell walls of fungi are similar to exoskeletons of insects because they are both made up of chitin. Chitin is made up of complex carbohydrates.
What protein is used in exoskeleton?
Chitin is the primary protein found in the exoskeletons of arthropods, such as insects, spiders, and crustaceans. It provides structural support and protection, serving as a tough, yet flexible material that makes up the outer shells of these animals.
What chemical makes up the shell of a crawfish?
Shells are primarily calcium, just like in human and animal bones.
What is a tough material that makes up an arthropods exoskeleton?
I believe that exoskeletons are made of the same material as our own fingernails and hair, just compacted together.
What is the hard matherial that makes up the bulk of your teeth?
enamel
What kingdom comprises of organisms with cell walls that has the same substance as that of the outer bodies of insects?
The kingdom fungi has organisms with cell walls made of chitin (the substance that makes up insect exoskeletons).
