Question

describe the location(where can they be found), structure(what is it composed/made of), function(what is its job/role) of proteins in one simple sentence for each one.

Answer 1

Location: Proteins are found everywhere in living organisms — inside cells (in the cytoplasm, membranes, and organelles) and outside cells (in body fluids and the extracellular matrix).
Structure: Proteins are made of long chains of amino acids that fold into specific three-dimensional shapes determined by their sequence.
Function: Proteins perform many jobs such as speeding up chemical reactions (enzymes), providing structure, transporting molecules, sending signals, and defending against infections.
