“10th Class Chemistry Chapter 13 Quiz: Biochemistry” discusses the chemistry of life at the level of molecules and reactions that support biological processes. This chapter is very important for MDCAT students because it serves as a link between chemistry and biology, covering topics that are very essential for medical and dental entrance exams. Our MDCAT Quiz for this chapter is designed to test your knowledge and enhance your understanding of biochemistry concepts.
The chapter starts with the introduction of biomolecules, classifying them into carbohydrates, proteins, lipids, and nucleic acids. It enables students to understand the structure, function, and importance of each class of biomolecules in living organisms. Carbohydrates are discussed as the major energy source, whereas lipids, as molecules, are discussed concerning their role in energy storage and cell membrane structure. Proteins, the basic building blocks, are discussed according to their roles in structure and enzymes. The concept of enzymes is elaborated upon, focusing on their role as biological catalysts and their functioning in metabolic reactions. Further, the importance of nucleic acids, such as DNA and RNA, is discussed in relation to heredity and the synthesis of proteins. Its applications in the real world have also been stressed upon in medicine, agriculture, food industries, etc.
