FAQs on Metabolites, Macro & Micro Molecules Video Lecture - Biology for JAMB

1. What are metabolites?
Ans. Metabolites are small molecules that are produced during metabolic processes in living organisms. They are the intermediates or end products of various biochemical reactions, such as the breakdown of nutrients or the synthesis of cellular components.
2. What is the difference between macro and micro molecules?
Ans. Macro molecules are large molecules made up of smaller units called monomers. Examples of macro molecules include proteins, nucleic acids (DNA and RNA), and polysaccharides. On the other hand, micro molecules are small molecules that are essential for various cellular processes, such as metabolites, vitamins, and hormones.
3. How do metabolites contribute to cellular functions?
Ans. Metabolites play crucial roles in cellular functions. They can act as building blocks for the synthesis of macromolecules, provide energy for cellular activities, regulate enzymatic reactions, and serve as signaling molecules for intercellular communication. Overall, metabolites are essential for maintaining the proper functioning of cells and organisms.
4. Can you provide examples of important metabolites in human metabolism?
Ans. Yes, some examples of important metabolites in human metabolism include glucose, which is a key source of energy; ATP (adenosine triphosphate), which is the primary energy currency in cells; amino acids, which are building blocks of proteins; and acetyl-CoA, which is involved in various metabolic pathways.
5. How are metabolites analyzed in scientific research?
Ans. Metabolites can be analyzed using various techniques in scientific research. Metabolomics, a subfield of systems biology, focuses on the comprehensive study of metabolites in biological systems. Techniques such as mass spectrometry and nuclear magnetic resonance spectroscopy are commonly used to identify and quantify metabolites in biological samples. These analyses provide valuable insights into metabolic pathways, disease mechanisms, and biomarker discovery.
