The correct answer is option 3: Apoenzyme. An enzyme is made up of two main components: a protein part and a non-protein part called a cofactor or a coenzyme. The protein part of the enzyme is known as the apoenzyme. Isoenzyme (option 1) refers to different forms of an enzyme that have similar functions but are found in different tissues. Holoenzyme (option 2) refers to the complete, active form of an enzyme that consists of both the apoenzyme and the cofactor/coenzyme. Therefore, it is incorrect to say that the holoenzyme is the protein part of the enzyme alone. Since option 4 includes all the options, it is not the correct answer as only option 3 represents the protein part of the enzyme.
