YES AND NO.
Firstly: A polyepeptide is a protein, constructed of many amino acids, coded for by the genetic code. (in triplets).
A cell produces many polypeptides--in other words proteins.__ These proteins (polypeptides) each have a specific purpose/role in the cell.For example, hameoglobin is a polypeptide. Proteins are basically refererd to as polypeptides, as they consist of many amino acids bounded together. POLY= MANY. Of some of the polypeptides (proteins) some are enzymes.
Enzymes catalyse reactions. Their poltpeptide shape--tertiary structure enables them to do this, as they have an active site which binds to the substrate. Each enzyme catalyses a specific substate.
Anyway, i think that's all you need to know.

What are oligomeric enzymes?
Contain 2 or more polypeptide chains associated by noncovalent forces.Homodimer , heterodimer or tetramer
What bio molecule is enzymes?
All the enzymes are protein or protein conjugates(with lipids or carbohydrates)
What is composed of polysaccharide and polypeptide?
a polysaccharide is the polymer of carbohydrates and a polypeptide is the polymer of a lipid.
How many polypeptide chains can be made from 9 amino acids?
3
Proteins can be made of several individual polypeptide chains true or false?
true
How could a change in a polypeptide affect cell activity?
Enzymes are derived from polypeptide chains, enzymes are responsible for adequate cell activity. Therefore, if a polypeptide chain is not properly composed, the enzyme will be dysfunctional, hence leading to a depletion in cell activity.
Composed of long chains of amino acids?
Polypeptide bonds....polypeptide bonds equal proteins ;)
What are oligomeric enzymes?

What bio molecule is enzymes?

What does chains of amino acids?
polypeptide chains!
What is polypeptide chains?
Chains of amino acids are referred to as polypeptides. Proteins are created from one or more of these polypeptide molecules.
Building block unit of a polypeptide chain?
Amino acids are the building block units of a polypeptide chain or a protein. These amino acids are linked together through peptide bonds.
What enzymes break down protein into amino acids?
Protease in general. Pepsin in the stomach and trypsin in the small intestine in mammals break down protein into polypeptide chains and erepsin in the small intestine break down polypeptide chains into amino acids.
How many polypeptide chains form the globin portion of the molecule?
4 polypeptide chains, each bound to a heme group to form hemoglobing
How does an enzyme?
Enzymes are made up of proteins. At a high temperature, the polypeptide chains of the enzyme are unfolded hence it loses its specific 3D configuration and active site, and is denatured.
What is composed of polysaccharide and polypeptide?
a polysaccharide is the polymer of carbohydrates and a polypeptide is the polymer of a lipid.
What is the componant of many lipids?
All lipids are composed of amino acids which make up polypeptide chains. Animals must have at least a small amount of lipids to survive.
