McCance Pathophysiology - The Cell. Chapter 1 Guide 2024

Cellular communication - Correct Answer "Cellular crosstalk" - how messages originate, are transmitted, received, interpreted, and read by the cell. It maintains cellular function and specialization. Intercellular signals - Correct Answer Allow each cell to determine its position and specialized role. Chemical fondness - Correct Answer Cell must demonstrate this for other cells and the environment in order to maintain the integrity of the entire organism. Absence of chemical fondness - Correct Answer Conversation brakes down and cells either adapt or become vulnerable to isolation, injury, or disease. Prokaryotes and Eukaryotes - Correct Answer Living cells are generally divided into these two major classes. Differ in chemical composition and biochemical activity. How Prokaryotes and Eukaryotes differ - Correct Answer Differ in chemical composition and biochemical activity, protein production and synthesis (due to RNA structural differences), enzyme content and mechanisms of transport on outer cellular membrane. Eukaryotes - Correct Answer The cells of higher animals and plants. Also, the single called organisms: fungi, Protozoa, and most algae. Eukaryotes have.. - Correct Answer Larger and more extensive intracellular anatomy and organization. Histones which bind with DNA and are involved in super coiling of DNA. Membrane bound intracellular compartments, called organelles (includes well-defined nucleus). Several chromosomes. Prokaryotes - Correct Answer Cyanobacteria (blue-green algae), bacteria, and rickettsiae. Prokaryotes have - Correct Answer No organelles. Nuclear material that is NOT encased by a nuclear membrane. No distinct nucleus. No histones (class of proteins). The nuclei of prokaryotes - Correct Answer Carries genetic info in a single circular chromosome. Differentiation - Correct Answer Or maturation. The process in which cells become specialized = different functions and cell type.
