Section outline

  • A Bohr model of the element Helium showing the positional relationship among electrons, neutrons, and protons.

    We need to study the cell's chemistry because the most minor, fundamental material components of the human body are chemical elements. These elements make up the organic and inorganic compounds needed by the body. It is also essential to understand what the changes in pH or the amounts of the necessary compounds can do to our bodies.

    Upon completion of this module, you will be able to:
    1. Name the four most important elements in the body. (CLO #1, #3, and #4)
    2. Distinguish between inorganic and organic compounds and be able to give characteristics of each type. (CLO #1, #3, and #4)
    3. List the properties of water that contribute to its physiological functions. (CLO #1 and #3)
    4. Describe the pH scale and its relationship to acidic, basic, and neutral solutions. (CLO #1, #3 and #4)
    5. Describe the structural organization and major functions of carbohydrates, lipids, proteins, and nucleic acid and how they work in the body. (CLO #1, #3, and #4).


    To achieve these objectives:

    1. Read the Module 2 Introduction. (MLO #1-5) (CLO # 1 and 3)
    2. Read Chapter 3 from the textbook. (MLO #1-5) (CLO #1 and 3)
    3. Test Your Knowledge sections are located at the end of each segment in the chapter. Answering the questions in these sections will aid in your knowledge to help you with the course. These questions will be relevant for information on testing and quizzes. (MLO #1-5)(CLO #1 and 3)
    4. Complete the exercises in the "Practice" section at the end of the chapter. (MLO # 1-5)(CLO 1-4)
    5. Complete the discussion activity. (MLO #3)(CLO 1-4)
    6. Complete the quiz. (MLO 1-5)(CLO 1-4)
