Chapter 27 Flashcards
Bacteria cell walls contain…
Peptidoglycan
Bacteria Cell Wall
Maintains cell shape
Provides physical protection
Prevents bursting in a hypotonic environment
What is perptidoglycan
A network of sugar polymers cross-linked by polypeptides
Gram-negative
Less peptidoglycan
Possibly toxic outer membrane
More likely to be antibiotic resistant
Genetic diversity factors
Rapid reproduction
Mutation
Genetic recombination
Exotoxins
Cause disease even when the prokaryotes that produces them aren’t present
Endotoxins
Released when bacteria die and their cell wall breaks down
Bioremediation
Use of organisms to remove pollutants
Uses of prokaryotes
Recovery of metal from ores
Synthesis of vitamins
Production of antibiotics and hormones
