multiple choice question proteins are macromolecules composed of numerous amino acids. based on this, which…

Brief Explanations:

Polymers are large - molecule compounds made up of many repeating subunits (monomers). Proteins are composed of numerous amino acids (which are monomers), so proteins are polymers. Colloids are a type of mixture, isomers have the same molecular formula but different structures, and monomers are the building - blocks of polymers, not the polymers themselves.

Answer:

C. Polymers
