    The lecture Bacteria by Vincent Racaniello, PhD is from the course Microbiology: Introduction. It contains the following chapters:

    • Bacteria and Bacterial Structure
    • The Gram-positive Solultion
    • The Gram-negative Solution
    • The Bacterial Interior
    • Making a Bacterial Cell
    • Fueling in Heterotrophs
    • Harnessing Bacteria
    • Bacteria Exchange DNA

    Included Quiz Questions

    1. The murein or the thick peptidoglycan layer passes the necessary molecules because they are hydrophilic.
    2. The outer membrane has pores in it that will allow small hydrophilic compounds to diffuse through.
    3. Large complexes get moved through transport complex proteins that are embedded in the membrane.
    4. Periplasmic spaces contain enzymes that can digest material as it comes through the outer membrane and transport it further on.
    5. The inner cell membrane has transport mechanisms that allow any materials that have been brought in to then get into the cytosol of the bacteria.
    1. It rotates like a fan and propels the bacteria forward and backwards based on energy stores and cellular nutrient requirements.
    2. It is usually made of amino acids or sugars.
    3. It's a determinant of the ability to colonize a specific niche, such as an organ or an outside environment.
    4. It protects the cell from drying out or desiccating.
    5. It is a defense mechanism against immune attack in that it protects from phagocytic cells which often try to engulf bacteria.
    1. Oxaloacetate and pyruvate.
    2. Carbon dioxide and lactate.
    3. Oxaloacetate and lactate.
    4. Pyruvate and carbon dioxide.
    5. Lactate and pyruvate.
