Question

Which is Not the characteristic of an enzyme?
1. Enzymes are biocatalyst
2. Enzyme activity is regulated
3. They are protein in nature
4. They bind to receptor and exert activity

Answer 1

Correct Answer - Option 2 : Enzyme activity is regulated

The correct answer is Enzyme activity is regulated.

 

• Enzymes speed up (catalyze) chemical reactions; in some cases, enzymes can make a chemical reaction millions of times faster than it would have been without it.
• Enzymes help the body break down larger complex molecules into smaller molecules, such as glucose, so that the body can use them as fuel.
• Enzymes help in DNA replication by unwinding the DNA coils and copying the information.
• Enzyme activity is not regulated. hence it is not characteristic of an enzyme.

 

Main characteristics of enzymes:

•  They are pH-sensitive.
• They are chemically proteinaceous in nature.
• They work best at optimum temperature.
