BIOL 1001 | 2026 Exam – 55 Questions on Organic Molecules, Carbohydrates, Proteins, Lipids | Louisiana State University

This exam review document contains 55 verified multiple-choice questions and answers from Chapter 3 of BIOL 1001 – General Biology at Louisiana State University, designed for the 2026 academic term. It focuses on the structure, classification, and biological roles of organic molecules, a foundational topic for students in biological sciences. Key areas covered include: Differences between organic and inorganic molecules Structure and function of carbohydrates, lipids, proteins, and nucleic acids Biological importance of monosaccharides, disaccharides, polysaccharides (e.g., glucose, fructose, cellulose, chitin) Dehydration synthesis vs. hydrolysis as mechanisms of macromolecule formation and breakdown Structure and function of enzymes, amino acids, and peptide bonds Detailed understanding of lipids (fats, oils, phospholipids, steroids), including hydrophobic interactions and membrane formation Overview of DNA and RNA, including their monomers (nucleotides), structure, and functional roles This material is highly recommended for students in biology, pre-med, nursing, nutrition, biochemistry, and life sciences, especially those enrolled in BIOL 1001, BIOL 1201, or related introductory biology courses. It is also useful for exam prep, review sessions, or students needing a conceptual refresher before tests. Every question is paired with a clearly marked, accurate answer, enabling effective self-assessment and targeted revision. The structured format ensures fast learning of biomolecule fundamentals and biochemical processes necessary for academic success.
