Introduction 1. This chapter provides a brief review of the basics of a cell, including cellular components, biological energy, and an overview of a cell’s natural life span. 2. Key Terms a. Cells – basic living, structural, and functional units of the human body b. Eukaryotic cells – multicellular organisms c. Prokaryotic cells – primitive cells d. Plasma membrane – sheet-like structure that encapsulates and surrounds the cell, allowing it to exist as a distinct unit 3. Figures and Tables a. Figure 1.1 – three-dimensional depiction of a typical mammalian liver cell II. Components of Cells A. Plasma Membrane 1. Sheet-like structure that encapsulates and surrounds the cell. It is asymmetrical and considered to be a fluid structure 2. Key Terms a. Hydrophobic – molecule or part of molecule that repels water but has strong affinity for nonpolar substances b. Receptors – macromolecules that bind a signal molecule with a high degree of specificity that triggers intracellular events c. Enzymes – protein catalysts that increase the rate of a chemical reaction in the body 3. Figures and tables a. Figure 1.2 – lipid bilayer structure of biological membranes b.
