  6. Since it’s not mentioned anywhere in sindh textbook of biology that co-factor is the only non protein part of an enzyme and it’s mentioned at the top of page that “prosthetic group is the non protien part of an enzyme. If it’s inorganic then it’s co-factor and if it’s organic then it is co-enzyme.” Prosthetic group is the right answer.
