Question

An activated enzyme consisting of polypeptide and a cofactor is known as:

Options
  • A

    Amylase

  • B

    Apoenzyme

  • C

    Holoenzyme

  • D

    Coenzyme

Explanation

Option A is incorrect because Amylase is the enzyme that breakdown carbohydrates.
Option B is incorrect because Apoenzyme is the enzyme with its cofactor removed it is non functional.
Option C is correct since Holoenzyme is an activated enzyme consisting of polypeptide and a cofactor.
Option D is incorrect because Coenzyme is a type of cofactor that loosely attached to the protein part.
