Reason: The secondary structure of a protein is according to amino acids present inside the polypeptide.   

Assertion (A): Co-enzyme is a nonprotein without which enzymes are inactive or incomplete.
Reason (R): Co-enzymes not only provide a point of attachment for a chemical group being transformed but also influence the properties of the group.
