What are the differences between protein and enzymes?

Let's do a quick definition first. Enzymes: molecules that perform the function of catalysis are called enzymes. I.e., it is a molecular definition based on function. Proteins: this is a molecular definition based on chemistry, i.e. read more

Proteins and enzymes are biological macromolecules, made up of many amino acids linked together as linear chains. Amino acid is the basic structural and functional unit of these macromolecules. An amino acid molecule is composed of four basic groups; namely, amino group, side chain (R- group), carboxyl group, and hydrogen atom, which are bonded to a central carbon atom. read more

Biological Difference: While enzymes catalyze reactions, proteins as a class of molecules, perform many functions, some examples: Transporter : ion channels, help in transporting molecules across cell membrane, hemoglobin transports oxygen co-operatively. Movement: actin and myosin are present in muscle cells. read more

Proteins and enzymes are two closely related names that are often misused. Both refer to biological macromolecules but the definition of each is based on different criteria . read more

Enzymes are proteins that are catalysts to the chemical reaction. Answer #3 (by: xDGoMuSiCxD) An enzyme is a catalyst, but a catalyst is not an enzyme. An enzyme is a protein that speeds up and/or causes chemical reactions to happen fast enough for a living thing (or an organism) to survive. For example, heat is a catalyst, but not an enzyme. read more

enzymes obey michaelis-menten kinetics(relation between substrate-enzyme interactions) , but proteins does not need to, since they are the building blocks of enzymes. there are possible situation like proteins acting as substrates to enzyme( milk-rennin). but an enzyme being a substrate to protein is unimaginable. read more
