Enzymes are very specific for the substances they act upon and cause their breakdown. For example, cellulase enzyme breakdowns cellulose, protease enzyme breakdowns proteins, pectinase enzyme breakdowns pectin, hemicellulose enzyme breakdowns hemicellulose and many more such enzymes are there. Enzymes are biological catalysts which increase the rate of reaction by lowering the energy of activation. High specificity is a characteristic feature of enzymes.
Hence, the statement given in the question is correct.
So, the correct answer is 'True'
