FMS 1 Cell Structure & Function (Week 1)
1.1 = the vehicle for transmission of genetic info in all organism
1.2 Theory by MJ Schleiden & T Schwann 1839
1.2.1 composed of 1/> cells
1.2.2 Exist before
1.2.3 Vital function
1.2.4 contain Hereditary info
1.3 Characteristic
1.3.1 Self-contained & Self-maintening
1.3.2 Need nutrient
1.3.3 nutrient --> energy
1.3.4 Specialized function
1.3.5 Reproduce
1.3.6 Stores its own activity instruction
1.3.7 Use protein as catalyst Amino acids bind and act as enzyme
1.3.8 Enclosed in plasma membrane across which nutrient & waste materials must pass
1.4 DNA
1.4.1 Components 4 nucleotides : A,C,T,G A <-> T, C <-> G Deoxyribose Phosphat compound
1.4.2 Structure Double helix
1.4.3 Herited
1.4.4 RNA translation PROCES ???
2 Prokaryotes
2.1 Cell Structure
2.1.1 Flagella = long, slender projection composed of microtubule, serve to propel the cell Types Monotrichous Peritrichous Amphitrichous Lophotrichous
2.1.2 Cell Wall = a fairly rigid layer surrounding the cell provide structural support, protection, filtering CLASSES Gram-negative inner membralikan -> periplasmic space -> peptidoglycan -> outer membrane -> porin protein -> LPS Gram-positive inner membrane -> peptidoglycan -> teichoic acid
2.1.3 Cell capsule = layer outside cell wall composed of polysaccharides serve to protect bacteria from phagoctosis
2.1.4 PLasma membrane = composed of protein & phospholipid, serve as permeability barrier, enzyme, transport solutes, energy generation (combined mitochondria), DNA anchoring, chromatid separation
2.1.5 Pili = composed of protein, for DNA transfer during conjugation
2.1.6 Ribosomes For protein synthesis
2.1.7 Chromosomes Genetic material
2.1.8 Plasmid Extrachromosomal genetic material
2.2 Multidrug resistance
2.2.1 Why ? Enzymatic deactivation of antibiotic Decreased cell wall permeability to antibiotic Altered target sites of antibiotic Efflux mechanism to remove antibiotic increased mutation
2.2.2 Solution Only use antibiotic for bacterial infection Use specific antibiotic for specific bacteria Don't stop antibiotics ASAP symptoms improve
3 Prokaryotes VS Eukaryotes
