Suggest and explain why the combined actions of exopeptidases and endopeptidases are more efficient than exopeptidases on their own.

Endopeptidases hydrolyse internal (peptide bonds) OR exopeptididases remove amino acids/hydrolyse (bonds) at the ends therefore there are more ends/increase in surfacae area for expopeptidases to work on.
