Question

Endopeptidase of the plant kingdom is
(a)Trypsin
(b)Pepsin
(c)Papain
(d)Urease

Answer 1

Hint: Endopeptidase is proteolytic peptidases which will break peptide bonds that are not at the end of the amino acid chain (that is within the molecule or internally ), in other hands the exopeptidases, which break peptide bonds from end-pieces of terminal amino acids(that is outside or at the end).

Complete answer:
Endopeptidase is the proteolytic enzyme that breaks the peptide chain at internal locations. They break peptide bonds of non-terminal amino acids (i.e. within the molecule), in contrast to exopeptidases, which break peptide bonds from the end-pieces. One example of this is often papain obtained from unripe papaya.

Additional Information:
 Papain may be a protease extracted from the raw fruit of the papaya plant. Proteolytic enzymes help in breaking the proteins into smaller protein fragments called peptides and amino acids. This is often why papain may be a popular ingredient in meat tenderizer. you'll get papain from eating raw papaya.

Endopeptidase	Exopeptidase
It is a type of protein hydrolysing enzymes that cleaves peptide bonds within the protein molecule.	It is the second type of peptidase enzyme that cleaves single amino acids at the terminals of the proteins.
Example: pepsin, trypsin, chymotrypsin etc.	Examples include Carboxypeptidase and aminopeptidase.
Synonyms: enterokinase or enteropeptidase.	Synonyms: Dipeptidases.
Results of the amino acid chain.	Results in the formation of monomers or single amino acids.

So, the correct answer is,” Papain”.

Note: Peptidase, also referred to as protease or proteolytic is an enzyme with a very important role within the hydrolysis of proteins. Hydrolysis is the process of breaking down bigger molecules into smaller parts, during this case from proteins deriving peptides and even smaller units called amino acids.
