FAQs on Introduction: Biomolecules Video Lecture - NEET

1. What are biomolecules?
Ans. Biomolecules are organic molecules that are essential for the structure, function, and regulation of living organisms. They include carbohydrates, lipids, proteins, and nucleic acids.
2. How are carbohydrates classified?
Ans. Carbohydrates are classified into three main groups: monosaccharides, disaccharides, and polysaccharides. Monosaccharides are the simplest carbohydrates and cannot be hydrolyzed into smaller carbohydrates. Disaccharides consist of two monosaccharide units linked together, while polysaccharides are composed of many monosaccharide units.
3. What are the functions of lipids?
Ans. Lipids have various functions in living organisms. They serve as a source of energy, provide insulation and protection for organs, act as structural components of cell membranes, and function as signaling molecules. Lipids also play a crucial role in the absorption and transport of fat-soluble vitamins.
4. How are proteins synthesized in cells?
Ans. Proteins are synthesized through a process called translation. During translation, the genetic information in DNA is transcribed into messenger RNA (mRNA). The mRNA then travels to the ribosomes, where it serves as a template for the synthesis of proteins. Transfer RNA (tRNA) molecules bring specific amino acids to the ribosomes, and the amino acids are joined together to form a protein chain.
5. What are the types of nucleic acids?
Ans. There are two types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is a double-stranded molecule that carries the genetic information in cells and is involved in the transmission of hereditary traits. RNA is mainly involved in protein synthesis and comes in different forms, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
