Penicillin inhibits peptide bridges in peptidoglycan
mycoplasmas: no cell wall
- causes walking pneumonia
-can't give them penicillin cause of lacking cell wall
Protoplasts - ✔✔CORRECT VERIFIED ANSWERS✔✔->>wall-less gram-
positive cells
spheroplast - ✔✔CORRECT VERIFIED ANSWERS✔✔->>wall-less gram-
negative cells
L-forms - ✔✔CORRECT VERIFIED ANSWERS✔✔->>wall-less cells that swell
into irregular shapes
,Acid Fast Cell Walls: - ✔✔CORRECT VERIFIED ANSWERS✔✔->>- like gram
positive cell walls
- waxy lipid (mycolic aid)
-mycobacterium
Nocardia: resist the decolorization with acid alcohol
Mycoplasmas - ✔✔CORRECT VERIFIED ANSWERS✔✔-
>>lack of cell walls sterols in plamsa membrane
smallest living cell
causes walking pneumonia
can't use penicillin
Archaea - ✔✔CORRECT VERIFIED ANSWERS✔✔->>wall less or wall of
pseudomurein
(lack NAM and D-amino acids)
What are the ways that you can damage the plasma membrane -
✔✔CORRECT VERIFIED ANSWERS✔✔->>-alcohol
- Quarternary ammonium products ex:
soap
, -antimicrobials ex:
polymexia
Isotonic Solutions - ✔✔CORRECT VERIFIED ANSWERS✔✔->>solute
concentrations equal inside and outside the cell
water is at equilibrium
hypotonic solution - ✔✔CORRECT VERIFIED ANSWERS✔✔->>solute
concentration is lower outside than inside the cell
water moves into the cell and eventually explodes
hypertonic solution - ✔✔CORRECT VERIFIED ANSWERS✔✔->>solute
concentration is higher outside of cell inside
water moves out of cell and will eventually become nothing
aka starving
3 types of transport protein - ✔✔CORRECT VERIFIED
ANSWERS✔✔->>uniport antiport symport-coupled
Uniport - ✔✔CORRECT VERIFIED ANSWERS✔✔->>protein can only transfer
1 type of molecule
