Question

A non-proteinaceous enzyme is
A. Lysozyme
B. Ribozyme
C. Ribonuclease-P
D. Both B and C

Answer 1

Hint: Enzymes are proteins which act as catalysts of biological systems and help to determine the patterns of chemical transformations. They are divided according to the type of reaction catalyzed into- oxidoreductases, transferases, hydrolases, lyases, ligases, and isomerases.

Complete answer:
Enzymes are catalysts that carry out chemical reactions at high rates within the mild conditions of temperature, pH, and pressure of the cells. Catalysis takes place at a specific site on the enzyme called the active site. Nearly all known enzymes are proteins.
Ribozymes are the RNAs that work as enzymes. Ligases, deoxyribonucleases, lysozymes are proteinaceous enzymes in order that they are made from proteins while ribozymes have RNA as structural components.
Enzymes accelerate reactions by factors of as maximum amount as millions and more. Indeed, most reactions in biological systems do not take place at perceptible rates within the absence of enzymes.
The catalytic activity of the many enzymes depends on the presence of small molecules termed cofactors, although the precise role varies with the cofactor and therefore the enzyme. Such an enzyme without its cofactor is called an apoenzyme; the complete, catalytically active enzyme is called a holoenzyme.

Therefore, the correct answer is option D, (both B and C). .

Note: Enzymes are used commercially and play an important role in our daily lives. They are used in the food, agricultural, cosmetic, and pharmaceutical industries to control and speed up reactions in order to quickly and accurately obtain a valuable final product. Enzymes show potential role in making cheese, brewing beer, baking bread, extracting fruit juice, tanning leather, and much more.
