Primary vs secondary metabolite

What is the primary function of primary metabolites?

• Attracting pollinators

• Essential for basic life processes and growth

• • Defense against herbivores

• • Synthesized in response to stress

Which of the following is an example of a primary metabolite?

• Alkaloid

• Terpenoid

• Flavonoid

• Amino acid

How are primary metabolites different from secondary metabolites in terms of abundance?

• • Primary metabolites are generally present in higher concentrations.

• Primary and secondary metabolites are equally abundant.

• Secondary metabolites are essential for basic life functions.

• Secondary metabolites are produced continuously.

What is a characteristic role of secondary metabolites?

• • Essential for basic life processes

• • Defense against herbivores and attraction of pollinators

• • Directly involved in growth and development

• • Synthesized under normal conditions

How are secondary metabolites regulated?

• • By enzymes in central metabolic pathways

• By specific enzymes or environmental factors

• They are not regulated

• Through continuous synthesis

Which of the following statements is true about the essentiality of secondary metabolites?

• • They are essential for basic survival.

• • They may provide advantages for adaptation and fitness.

• • They are produced continuously.

• • They are building blocks for proteins.

What is an example function of primary metabolites?

• Defense against herbivores

• • Attraction of pollinators

• • Building blocks for proteins, nucleic acids, and cell structures

• • Response to environmental stress

In what conditions are secondary metabolites synthesized?

• Continuously under normal conditions

• • In response to stress, environmental changes, or specific cues

• • During growth and development

• • In equal proportions with primary metabolites
