Module 1 - Foundations of Microbiology and Lab Safety – Chapters 1 & 2:
Know the various classes of microorganisms and unique features and characteristics of each:
Bacteria- one of the two domains of prokaryotes; all medically important prokaryotes are in the domain Bacteria. bacteria are single-celled or noncellular spherical or spiral or rod-shaped organisms that reproduce by fission.
Protozoans-Group of single-celled eukaryotic organisms. protozoans are colorless mobile organisms. They feed on other organisms for their source of energy.
Fungi-A non-photosynthetic eukaryotic heterotroph. fungi can consist of yeast, mold, and mushrooms. They are not microbes. Some are pathogenic and can cause disease in humans and animals.
Viruses-Acellular or non-living agent composed of nucleic acid surrounded by a protein coat.
Prions-Infectious protein that has no nucleic acid.
Describe characteristics and importance of the four major macromolecules – review the structure of each macromolecule (what they are comprised of) as well as examples:
Carbohydrates-Compounds containing principally carbon, hydrogen, and oxygen atoms in a ratio of 1:2:1. Are a group of organic compounds in foods and living tissues and consist of sugars, starch, and cellulose. They can be broken down to release energy in the body
Proteins-Macromolecule containing one or more polypeptide chains. are nitrogenous organic compounds that have one or more amino acid chains. They are structural components of body tissues, enzymes and antibodies
Lipids-One of a diverse group of organic substances all of which are relatively insoluble in water, but soluble in alcohol, ether, chloroform, or other fat solvents. are organic compounds of fatty acids, which are insoluble in water and soluble in organic solvents.
Nucleic acids-Ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). are a complex organic
