    metabolites:
    A Are essential to microbe function Correct Answer Incorrect Answer
    B Are by-products of metabolism not important to microbe function Correct Answer Incorrect Answer
    C Require additional processing before packaging Correct Answer Incorrect Answer
    D Are harvested during exponential growth Correct Answer Incorrect Answer

    Solution

    Secondary metabolites (e.g., antibiotics, pigments) are non-essential compounds produced during the stationary phase. They aid survival (e.g., antimicrobial defense) but are not required for basic growth.
