BIL 160 Lecture Notes - Lecture 12: Neuromuscular Junction, Exotoxin, Antibiotics
Document Summary
What do all three forms of sexual reproduction have in common (i. e. , what is it that makes these modes. Endospore: dormant phase: species can form a tough environment resistant structure called an endospore that cane survive extremes of temperature and drought. Is a little more than the dna surrounded by a thick wall, extremely difficult to kill. Invasion of tissue: exotoxin their toxins block inhibitory neurotransmitters at the neuromuscular junction, causing constant stimulation of muscle contraction, endotoxin - part of plasma membrane (primarily in g- bacteria) Antibiotics: substances that inhibit the growth of prokaryotic cells, antibiotics are not effective against viruses nor eukaryotic pathogens, bacteriostatic substance inhibits the growth of bacterial culture, bactericidal substance kills bacteria, 4 groups of mechanisms of actions. Inhibition of enzymes involved in cell wall biosynthesis. Interference with normal nucleic acid (dna , rna) function and repair.
