Co-factor and prosthetic groups are __________ compounds, ________ bound to apoenzyme.
Options
- Aorganic, transiently
- Binorganic, tightly
- Corganic, tightly
- 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
