B
mostly made up of carbohydratesand is produced by living cell organism
C
mostly made up of lipidsand is produced by living cell organism
Explanation: 

Detailed explanation-1: -1 Introduction to Enzymes. Enzymes are protein biopolymers formed in all living cells from the 20 natural amino acids. Within a cell, enzymes act as biocatalysts driving numerous chemical reactions and coordinating various cellular functions.

Detailed explanation-2: -Enzymes are large proteins and, like other proteins, they are produced in living cells of plants, animals and microorganisms. All living organisms require enzymes for growth and for the production andutilization of energy which is essential for life.

Detailed explanation-3: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes.

Detailed explanation-4: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.

Detailed explanation-5: -Answer and Explanation: Protein enzymes are produced by ribosomes, which are located in the cytosol and attached to the rough endoplasmic reticulum, suspended as part of the RNA-to-protein translation process.
