bacteria may come together in one cell, thus allowing for recombination mechanism for adenosine triphosphate (ATP) production in high-energy phosphate bonds produced by the central metabolic pathways are donated to adenosine diphosphate (ADP) to form ATP is: substrate-level phosphorylation pathway that generates ATP by phosphorylation that does not require oxygen and produces various end products, including alcohols, acids, carbon dioxide, and hydrogen, is: fermentative metabolism pathway of metabolism that involves a series of electron transfers from reduced carrier molecules such as and NADPH2 to a terminal electron acceptor is oxidative phosphorylation term used when oxidative phosphorylation uses oxygen as the terminal electron acceptor is: aerobic respiration organelle is found in eukaryotic cells and is responsible for controlled enzymatic degradation of intracellular substances Lysosomes acids are glycerol- or ribitol-phosphate polymers that are combined with various sugars, amino acids, and amino sugars, which are a part of the cell wall of gram-positive bacteria. of DNA that move from plasmid to chromosome or vice versa but are not found as separate entities are called: transposable elements genes within an organism make up that organism’s genome bacterial cell that contains teichoic acid stains which color on the Gram stain? Purple bacterial cell that contains an membrane and periplasmic space stains pink to red on Gram stain. Which one of the following statements explains this discrepancy No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition. acids, fatty acids, sugars, and nucleotides are produced during which metabolic reaction? Biosynthesis
example of a selective medium for organisms is? colistin and nalidixic acid. air, which contains 21% oxygen (O2) and a small amount (0.03%) of carbon dioxide (CO2), is the environmental condition that best suits which type of organism? Aerobes concentrations of CO2 (5% to 10%) and approximately 15% O2 produce an environmental condition that best suits which type of organism? Capnophiles 5% and 10% hydrogen (H2), 5% to 10% CO2, 80% to 90% nitrogen (N2), and 0% O2 produce an environmental Anaerobes O2 (5% to 10%) and increased CO2 (8% to 10%) produce an environmental condition that best Microaerophiles of Streptococcus pneumoniae appear alpha-hemolytic on blood agar media. Which one of the following statements explains this discrepancy? No discrepancy is present. S. pneumoniae should be on blood agar. example of a beta-hemolytic organism is? Staphylococcus aureus. specimen is quantitatively plated by using a calibrated loop? specimen culture, if positive, should be immediately reported to the clinician? Blood appropriate storage for a cerebral spinal fluid specimen is ____° C? 37 microscopy, resolution is defined as the: Extent to which detail in the magnified object is maintained is contrast in microscopy most commonly achieved? By staining techniques 1st step in gram stain sequence is the application of, which is the primary stain? Crystal violet mordant that is applied after the primary stain to bond chemically the alkaline dye to the bacterial cell wall is: Gram's iodine which step in the Gram-stain procedure are gram positive bacteria 1st distinguished from gram negative bacteria? Gram's decolorizer The acid fast stain is specifically designed for bacteria whose cell walls contain: Mycolic positive positive hemolytic
