ENZYMES
“All enzymes are not proteins.” This statement is justified by:
| A |
All enzymes do not follow the Michaelis Menton hypothesis |
|
| B |
RNAs act as ribozymes |
|
| C |
Antibodies take part in the catalysis of many reactions |
|
| D |
Metals are involved in attachment to enzymes and catalysts |

Ribozymes are RNA molecules with catalytic activities, which acts upon phosphodiester bonds in RNA & cause its hydrolysis lintron splicing event.
RNAs are not protein, but meet all the classic criteria of enzymes therefore all enzymes are not protein
Coenzymes are…………..organic compounds :-
| A |
Lipoprotein |
|
| B |
Proteinaceous |
|
| C |
Non-protein |
|
| D |
Any of the above |

Enzymes are mainly proteins, that catalyze (i.e., increase the rates of) chemical reactions with the exception of catalytic RNA molecules, or ribozymes.
In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products.
