Answers (1)

  • The enzyme exists in its active form as a holoenzyme.
  • The apoenzyme and the coenzyme are their two components. A cofactor is referred to as a coenzyme if it is a natural, organic molecule. 
  • The apoprotein is inactive on its own. It becomes active upon binding to the cofactor, resulting in the formation of a functional holoenzyme. 

Therefore, option 2 is the correct answer.
