The flexible protein fibers that make up a sponge are called spongin. The hard, tiny spikes found in sponges are called spicules, and they are made of silica or calcium carbonate.

protein
Makes up the code for living things
Enzymes are a type of protein.
It changes shape because the water which absorbes into the sponge makes the sponge ore spongey to be squashed and moveable.
A polypeptide chain is made up amino acids that form from a peptide bond. The polypeptide chain makes up a protein; therefore, the type of protein is contingent on the number of chains present.
Keratin is the protein that makes up hair. This protein also makes fingernails.
protein that makes up thin myofilament
Protein makes up enzymes, hair, and nails.
The thick myofilaments are formed from a protein called myosin.
