BIOS 256 – Exam 2 Review (60+ Questions) – Metabolism, Vitamins, Hormones, Renal & Urinary Systems – Chamberlain University

This document is a targeted Exam 2 review guide for BIOS 256: Human Anatomy and Physiology IV at Chamberlain University, covering the 2025/2026 academic year. It features 60+ fully solved questions and short essay-style responses across high-yield topics such as metabolism, hormone regulation, renal physiology, and urinary system anatomy. Answers are direct and accurate, ideal for quick reference and exam-focused study. Topics include: Metabolism and energy pathways: definitions and differences between anabolism and catabolism, glycolysis, Krebs cycle, electron transport chain, and ATP yield from aerobic respiration Biochemical processes: gluconeogenesis, glycogenolysis, lipogenesis, lipolysis, fermentation, and vitamin classifications (fat vs. water soluble) Hormonal regulation: roles of insulin, glucagon, ADH, aldosterone, angiotensin II, and parathyroid hormone in metabolic and renal homeostasis Renal and nephron physiology: glomerular filtration, GFR regulation via RAA system, countercurrent exchange, water and sodium reabsorption, filtrate flow through the nephron Urinary system anatomy: kidney structures (nephron parts, vasa recta), urinary tract (ureters, bladder, urethra), and differences in male urethra Clinical concepts: type 1 diabetes signs, waste products in urine, and hormone effects on kidney function This document is best suited for: BIOS 256 students preparing for midterm or unit exams Pre-nursing and allied health students needing a structured, simplified review of metabolism and urinary physiology Learners who prefer fast-paced Q&A formats for memorization and application Anyone preparing to answer both MCQs and short-answer questions efficiently Each entry is carefully worded for conceptual clarity and test preparation, offering a complete summary of renal, metabolic, and endocrine interactions in human physiology.
