Co-factor and prosthetic groups are __________ compounds, ________ bound to apoenzyme.

Options

  1. Aorganic, transiently
  2. Binorganic, tightly
  3. Corganic, tightly
  4. Dinorganic, transiently

Correct answer

C. organic, tightly

Step-by-step solution

Enzymes are proteinaceous in nature. Some Enzymes also contain non-protein part known as Co-factors. These factors are attached to the Enzymes to enhanced their catalytic activity. The protein part of Enzyme is known as Apoenzyme. Hence Apoenzyme (Protein part) + Co-factors (Non protein part) = Holoenzyme (Whole Enzyme). As the co-factors are bound to enzymes, the removal of these factors affects the overall activity of Enzymes too. These co-factors can be organic or inorganic. Organic cofactors if tightly bound ar
