Q & A

What is metabolism and why is it important for living organisms?

Metabolism is a collection of chemical processes that occur within living organisms to maintain life. It involves thousands of chemical compounds, known as metabolites, which are essential for various biological functions.

What are the two main types of metabolites?

The two main types of metabolites are primary metabolites, which are essential for growth and development, and secondary metabolites, which support life but are not vital for basic metabolic processes.

What role do primary metabolites play in organisms?

Primary metabolites, such as carbohydrates, proteins, and lipids, are produced by organisms and are crucial for cellular metabolism, providing energy and structural components necessary for survival.

How do secondary metabolites differ from primary metabolites?

Secondary metabolites are not directly involved in growth, development, or reproduction but serve ecological functions, such as defense against pests and competition with other plants. They often vary between species and are not essential for the organism's survival.

What are some examples of secondary metabolites and their functions?

Examples of secondary metabolites include alkaloids, which defend plants against herbivores, and flavonoids, which have antioxidant properties. Other functions include attracting pollinators and protecting against environmental stresses.

What techniques can be used to increase the production of secondary metabolites?

Techniques to enhance secondary metabolite production include cell selection in tissue culture, elicitation using abiotic or biotic elicitors, and employing hairy root cultures through Agrobacterium rhizogenes.

What is the significance of using elicitors in tissue culture?

Elicitors are substances that can stimulate the production of secondary metabolites in cultured plant cells, enhancing their ability to produce valuable compounds for pharmaceutical and agricultural applications.

How does the composition of growth media affect metabolite production?

The formulation of growth media can significantly influence metabolite production as different plant species have unique nutrient requirements, and the composition of the media can either support or hinder metabolic processes.

What is the relationship between primary and secondary metabolites?

Primary metabolites are essential for basic life processes, while secondary metabolites are often derived from modifications of primary metabolites and serve specific ecological functions, contributing to the plant's interaction with its environment.

What challenges exist in the large-scale production of secondary metabolites?

Challenges include understanding the cellular biosynthetic pathways, ensuring optimal growth conditions, and managing the economic viability of producing these compounds on a commercial scale, especially when using tissue culture techniques.
