APHY 101 Midterm Chapters 1–6 2026/2027 | 100+ Questions & Answers | Cells, Chemistry, Metabolism, Tissues & Integumentary System

This comprehensive APHY 101 Midterm Chapters 1–6 2026/2027 study resource contains 100+ exam-style questions and answers across 20 pages, focusing on the foundational material commonly assessed during the first half of an introductory Anatomy and Physiology course. It begins with the differences between anatomy and physiology, levels of biological organization, metabolism, homeostasis, negative feedback, anatomical position and serous membranes before progressing into chemistry, cellular biology, metabolism, genetics, histology and the integumentary system. The chemistry section provides focused revision of atoms, elements, molecules, compounds, ions, isotopes, atomic number and atomic weight, electrolytes, acids, bases and the pH scale. Students also review carbohydrates, lipids, proteins and nucleic acids, including saturated versus unsaturated fats and the primary, secondary, tertiary and quaternary levels of protein structure. This material establishes the chemical foundation needed to understand cellular structure and physiological processes. The cellular biology portion covers the cell membrane, nucleus, cytoplasm, organelles and selective permeability, followed by membrane-transport mechanisms including simple diffusion, facilitated diffusion, osmosis, filtration, active transport, endocytosis, pinocytosis, phagocytosis, receptor-mediated endocytosis, exocytosis and transcytosis. The resource also addresses isotonic, hypotonic and hypertonic conditions, the cell cycle, cellular differentiation, tumors, stem cells and progenitor cells. Metabolism and molecular biology receive additional attention through anabolism, catabolism, dehydration synthesis, hydrolysis, enzymes, cofactors, coenzymes, ATP and cellular respiration. The questions extend into DNA and RNA, genes, chromosomes, the genome, codons, anticodons, mutations and mutagens, providing students with a concise review of the relationship between cellular metabolism, genetic information and protein production. The histology material reviews epithelial, connective, muscle and nervous tissues, along with tight junctions, desmosomes, gap junctions, basement membranes, exocrine glands, extracellular matrix, fibroblasts, macrophages, mast cells and collagenous, elastic and reticular fibers. These concepts transition into a substantial examination of the integumentary system, including the epidermis, dermis and subcutaneous layer; skin functions and pigmentation; hair and nails; sebaceous, eccrine, apocrine, ceruminous and mammary glands; wound healing; burns; the rule of nines; aging-related skin changes; and basal cell carcinoma, squamous cell carcinoma and melanoma. The subject coverage corresponds to foundational topics found in standard undergraduate Anatomy and Physiology references such as Betts et al., Anatomy and Physiology 2e (OpenStax, 2022), particularly its coverage of the chemical level of organization, cellular level of organization, tissue level of organization and integumentary system. Students should use the uploaded material as an exam-preparation and active-recall resource while verifying course-specific definitions and any incomplete answers against their assigned textbook, lectures and instructor materials. Relevant students: This document is especially relevant to students enrolled in APHY 101, Anatomy and Physiology I, Human Anatomy and Physiology I, or equivalent introductory A&P courses. It can support nursing and pre-nursing students, allied health and health sciences students, biology majors, medical assisting students, radiography students and learners completing Anatomy and Physiology prerequisites for other healthcare programs. The uploaded document does not specify a university or institution, so no university name has been invented.
