NEET 2022, Chemistry Q28: Proteins

NEET2022Chemistry
Q.

The incorrect statement regarding enzymes is:

  1. A

    Like chemical catalysts enzymes reduce the activation energy of bio processes.

  2. B

    Enzymes are polysaccharides.

  3. C

    Enzymes are very specific for a particular reaction and substrate.

  4. D

    Enzymes are biocatalysts.

Solution

Enzymes are proteins (built from amino acid monomers), not polysaccharides (built from sugar monomers). Hence statement (2) is incorrect.

The other statements are correct: enzymes act as biocatalysts that lower activation energy and exhibit pronounced specificity for substrates and reactions.
