Question

Which is not true for enzymes?

• A. Enzyme is a complex structure of protein.
• B. Enzyme can be regulated by specific molecules.
• C. Enzyme is non-sensitive for the changes of temperature and pH.
• D. Enzyme functions as catalyst for various reactions.

Answer 1

The correct option is C Enzyme is non-sensitive for the changes of temperature and pH.

Enzymes are complex biomolecules made up of proteins. Few RNA molecules are catalytic in nature. They are called as ribozymes but mostly enzymes are macromolecules made up of proteins. Enzymes are biological catalysts and function at physiological pH and temperature. They are inactive at extremes of temperature and pH. Enzymes are biological catalysts and catalyze metabolic reactions in living systems. Enzymes can be regulated by specific molecules called as allosteric modulators, the allosteric modulators bind on separate allosteric sites to enzymes. Those enzymes having allosteric site are called as allosteric enzymes.
