 Topic:

Enzymes

 Question:

Which of the statement regarding enzymes is NOT true?

 Options:

  • Some enzymes have metal ions as co-factors
  • Enzymes are compounds of hundreds of amino acids
  • Enzymes have globular structure
  • Enzymes alter the nature and properties of end products

 Correct Answer:

 Enzymes alter the nature and properties of end products

 Explanation:

Some important properties of enzymes are given below:

  1. They are globular proteins, which is one reason why we need protein in our diet.
  2. They are all biological catalysts. They speed up a reaction without being used up; this means they can be used over and over again.
  3. They do not alter the end products of chemical reaction.
  4. A small amount of enzyme can affect the change of a large amount of chemical.
  5. The way enzymes work is affected by temperature, PH and pressure. They can be denatured (destroyed) by excessive heat.
  6. The reaction is reversible.
  7. Enzymes are specific that is they control only one reaction. So maltase only acts on maltose, sucrose on sucrose etc.
