BIO 108 Exam 2 Study Guide UMKC 2026 220 Questions – Metabolism Photosynthesis Cell Cycle Enzymes Answers, Biology University of Missouri–Kansas City

This document contains approximately 220 exam questions with verified answers for BIO 108 Exam 2 at the University of Missouri–Kansas City (UMKC), focusing on metabolism, thermodynamics, cellular respiration, photosynthesis, enzyme function, and the cell cycle. The content is structured in a detailed question-and-answer format, making it highly effective for exam preparation, practice, and mastering complex biological concepts. The material provides comprehensive coverage of thermodynamics and energy transformations, including the first and second laws of thermodynamics, entropy, and Gibbs free energy relationships (page 1). It also explores enzyme function in depth, including activation energy, enzyme regulation, and catalytic activity, helping students understand how biochemical reactions are controlled (pages 2, 19). A significant portion focuses on cellular respiration and metabolism, including glycolysis, the Krebs cycle, oxidative phosphorylation, and ATP production. It explains redox reactions, NAD+/NADH cycling, proton gradients, and chemiosmosis, along with ATP yield calculations and energy coupling (pages 5, 8–9, 20). These sections are essential for understanding energy production and utilization in cells. The document also thoroughly examines photosynthesis, including light reactions in the thylakoid membranes, the Calvin cycle in the stroma, and adaptations such as C3, C4, and CAM pathways. It highlights pigment absorption, electron flow (cyclic vs noncyclic), and factors affecting photosynthetic efficiency (pages 3, 9–11). Additionally, the material covers genetics and cell division, including mitosis, meiosis, chromosome behavior, independent assortment, crossing over, and cell cycle regulation (G1, G2, checkpoints, CDKs). It also addresses DNA content changes, chromatid separation, and cancer-related topics such as tumor types and cell cycle disruption (pages 4, 12–13, 18). Further sections include applied problem-solving questions involving ΔG calculations, ATP energetics, and metabolic predictions, helping students develop analytical and quantitative skills required for exams (pages 5–6, 17). These features make the document particularly valuable for higher-level understanding and application-based questions. This resource is ideal for undergraduate students enrolled in BIO 108, General Biology, Cell Biology, Molecular Biology, and Life Sciences courses, particularly at the University of Missouri–Kansas City. It is especially useful for students preparing for Exam 2, midterms, or cumulative assessments. It may also benefit advanced high school students taking AP Biology or equivalent courses. The content aligns closely with widely used textbooks such as Campbell Biology by Lisa A. Urry et al., particularly chapters on metabolism, cellular respiration, photosynthesis, and the cell cycle. It serves as an excellent companion to lectures, textbooks, and study guides.
