Which of the following is not an attribute of enzymes [NCERT 1976; CPMT 1985]
A) They are proteinaceous in nature
B) They speed up the rate of biochemical reactions
C) They are specific in nature
D) They are used up in reactions

Answer 1

D)they are used up in reactions...
hope u got help ...

Answer 2

D) They are used up in reactions.

Enzymes are biological catalysts that are made up of proteins.Since they are made up of proteins, they are proteinaceous in nature. They are catalysts and therefore increase the speed of biochemical reactions. Each enzyme have a specific function for which they act as biological catalysts.Hence they are specific in nature.

Enzymes acts as biological catalysts in biochemical reactions.They are not used up.They are reusable.

Thus they are not used up in reactions.
