Q. Which of the following statements regarding Co-enzymes is/are correct?
  1. They assist in biochemical transformations
  2. They are organic molecules comprising C, H, O and N
  3. Most of Co-enzymes are Proteins
Select the correct option from the codes given below:

Answer: Only 1
Notes: Co-enzymes are non-protein organic molecules that assist enzymes in biochemical transformations. They often contain elements like C, H, O, and sometimes N or P, but not all necessarily do. Most co-enzymes are not proteins; rather, they are derived from vitamins or are small organic molecules associated with enzyme activity.
