“11th Class Biology Chapter 2 Quiz: Biological Molecules” throws light on the structure, function, and importance of those molecules that are the basis of life. To MDCAT students, this chapter is indispensable because it covers important biological concepts necessary to understand metabolic processes, energy production, and molecular interactions. Our MDCAT MCQs of this chapter contain a test series that will assist you in attempting questions related to this chapter for MDCAT.
The opening of the chapter introduces biological molecules, which consist of organic compounds essential for life: carbohydrates, lipids, proteins, and nucleic acids. Each class has been dealt with in detail about their structure and functions, along with examples of their biological significance. Carbohydrates, on the other hand, are mostly presented as energy-containing molecules, their examples including monosaccharides (such as glucose), disaccharides (like sucrose), and polysaccharides (including starch and glycogen).
The chapter also explains lipids, which include fats, oils, and steroids. Lipids are important for energy storage, insulation, and membrane formation. Emphasis is given to the role of fatty acids, glycerol, and phospholipids in maintaining the structural integrity of cell membranes. Similarly, the chapter explores proteins, which are made up of amino acids. Students will learn about the structure of proteins, including primary, secondary, tertiary, and quaternary structures, as well as their roles in enzymes, hormones, and structural components.
The last group of biological molecules covered is nucleic acids—DNA and RNA—which are the carriers of genetic information. The chapter talks about the structure of nucleotides and how they form the backbone of nucleic acids. The role of DNA in storing genetic information and RNA in protein synthesis is explained, along with the importance of ATP (adenosine triphosphate) as the energy currency of the cell.
