In secondary metabolism two distinct phases- trophophase and idiophase refer respectively to
-
- Growth and production phase
- Early and late phase
- Primary and secondary metabolism
- Lag phase and log phase
Correct Option: A
In secondary metabolism two phases are apparent: trophophase and idiophase. Trophophase is the growth phase of the culture; idiophase is the time when the secondary metabolites are formed. The success of the idio-phase is dependent on the trophophase.
