Which of the following are not secondary metabolites in plants?

  1. Rubber, gums
  2. Morphine, codeine
  3. Amino acids, glucose
  4. Vinblastin, curcumin

Answer

(3) Amino acids, glucose

Solution

As per NCERT, secondary metabolites include alkaloids (morphine, codeine), polymeric substances (rubber, gums, cellulose) and drugs (vinblastin, curcumin).

Amino acids and sugars such as glucose have identifiable functions in normal physiological processes ⇒ they are primary metabolites.
