MICROBIO DR FINGER
test number one
| Question | Answer |
|---|---|
| Smallest unit of an element, consists on protons neutrons and electrons, each element has different numbers of e p and n | Atoms |
| Protons + plus neutrons o | Atomic mass |
| Cloud/ shell circling nuclues 1. Allow interactions/reactions to form molecules | Electrons - |
| Shared pair of electrons- = 1 bond | Covalent bonds |
| First make ion 1. Opposite charges | Ionic bonds |
| Ions in water | Electrolytes |
| Donate H+ to solution | Acids |
| Donate -OH to neutralize or lower H+ | Base |
| Carbon molecules- molecules of life | Organic molecules |
| Monosacchride | 1 ring |
| Disaccharide, made by dehydration synthesis, ade by hydrolysis | 2 ring |
| Polysaccharide Ex--starch glycogen cellulose | Multipule ring |
| 3 fatty acids on glycerol | Triglycerides |
| 2 fatty acids on glycerol | Phospholids |
| Ringed hydrophobic Ex-- cholesterol | Steroids |
| 2 AA bound together Tripeptide, polypeptide, protein ( functional) | Dipeptide |
| Something that gets in the way of the fold | Denaturation |
| Specific proteins that allow biochemical metabolism Ex-- antibodies | Enzymes |
| Have cell membrane, cytoplasm, DNA, ribosomes | All cells |
| Cultivate or starting a culture of a small sample in/ on media | Inoculate |
| Spread out cells on plate Petri plate with agar Pour plate also | Isolation |
| 37 degrees Celsius usually best | Incubate |
| Macroscopically see with naked eye Colony morphology | Inspect |
| Cell shape (size) Stain cell walls | Microscopically |
| What does it metabolize or what can it handle | Biochemically |
| Each species will have its own characteristics ( colony color, size, cell shape, gram stain, metabolism) | Identify |
| Color change vs. selective (dies or lives) or both | Differential media |
| Shapes of cells | Cocci, bacilli, spirilli |
| Single or Multipule, aids in motility | Flagella |
| Hair like projections | Fimbrine |
| Larger projections, adhesion to other bacteria for conjunction | Pili |
| Slime layer aids in adhering to surfaces, protects from white blood cells, participation in biofilms | Glycocalyx |
| Determins shape | Cell wall |
| Selectivly permeable | Cel membrane |
| Regulates food and waste | Transporters |
| Spheres | Coccus |
| Rod | Bacillus |
| Short rod | Coccobacillus |
| Bent | Vibrio |
| Spiral | Spirilli |
| Spirilli with flagella | Spirocletts |
