Question

proteins
monomer
elements that make this macromolecule up
function/job
examples

Explanation:

Proteins are macromolecules. Their monomers are amino - acids. They are made up of elements such as carbon, hydrogen, oxygen, nitrogen and sometimes sulfur. Proteins have various functions like catalyzing reactions (enzymes), providing structural support (collagen), transporting substances (hemoglobin). Examples include enzymes like amylase, structural proteins like keratin in hair and nails, and transport proteins like transferrin.
