Read the following statements and choose the correct option: 1. Carotenoids, anthocyanins, etc are pigments which are secondary metabolites 2. Concanavalin A is an Alkaloid 3. Morphine, Codeine, etc are classified under drugs. 4. The acid insoluble pool represents roughly the cytoplasmic composition. 5. Secondary metabolites have identifiable functions and play known roles in normal physiologial processes

Step-by-step solution

In secondary metabolites, carotenoids, anthocyanins, etc are pigments. Concanavalin A is a lectin. Morphine, Codeine, etc are alkaloids while Vinblastin, curcumin, etc are drugs.,When nitrogenous bases attached to a sugar, they are nucleosides. If a phosphate group is also found esterified to the sugar they are called nucleotides. Nucleic acids like DNA and RNA consist of nucleotides only
