BIO 108 Unit 2 UMKC 2026 200 Questions – Cellular Respiration Photosynthesis Mitosis Meiosis Answers, Biology University of Missouri–Kansas City

This document contains approximately 200 exam questions with verified answers for BIO 108 Unit 2 at the University of Missouri–Kansas City (UMKC), focusing on cellular respiration, photosynthesis, enzyme activity, thermodynamics, and cell division processes. The content is presented in a structured question-and-answer format, making it highly effective for exam preparation, practice, and mastering core biological processes. The material provides in-depth coverage of cellular respiration, including glycolysis, the Krebs cycle, oxidative phosphorylation, and ATP production. For example, as outlined on page 2, glycolysis and fermentation occur in the cytosol, while the Krebs cycle takes place in the mitochondrial matrix. It also explains key outputs such as NADH, FADH₂, CO₂, and ATP, along with the role of oxygen as the final electron acceptor in the electron transport chain (pages 2, 15). A significant portion focuses on photosynthesis, including light reactions in the thylakoid membranes and the Calvin cycle in the stroma (page 9). The document highlights key products such as ATP, NADPH, and oxygen, as well as adaptations like cyclic electron flow and photorespiration under high-temperature conditions (pages 2, 7, 16). It also explains how sunlight serves as the ultimate energy source for organic molecule synthesis. Additionally, the document thoroughly examines enzyme function and metabolism, including activation energy (EA), coupled reactions, and thermodynamic principles such as entropy (S) and free energy (ΔG). It explains how exergonic and endergonic reactions interact, and how energy transformations drive cellular processes (pages 1, 3–4). Further sections provide detailed coverage of cell division, including mitosis, meiosis, and the cell cycle. It explains stages such as prophase, metaphase, and anaphase, along with key concepts like homologous chromosomes, crossing over, independent assortment, and chromosome behavior (pages 3, 8, 12). It also highlights regulatory mechanisms such as checkpoints and differences between mitosis and meiosis. The document also integrates applied biological concepts such as anaerobic vs aerobic metabolism, fermentation pathways, and organism classification (e.g., facultative anaerobes and strict aerobes), providing real-world context for metabolic processes (pages 5–6, 11). 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 Unit 2 exams, 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 cellular respiration, photosynthesis, and the cell cycle. It serves as an excellent companion to lectures, textbooks, and study guides.
