metabolism Flashcards
what are the products of fermentation
ATP + NADH
what are essential when E.coli infects the urinary tract
gluconeogenesis and TCA cycle
what do glycolysis and entner-doudoroff pathway result in
growth in the intestinal tract
what does pathogenic listeria utilise to promote growth
utlisation of host sugar phosphate via specific transporter activated in host => promote rapid intracellular growth
what are the main functional subunits of aerobic respiration
-ubiquinone (Q)
-NADH dehydrogenase complex
-cytochrome C
in anaerobic respiration what enzyme replaces cytochrome
reductase enzyme
what are characteristics of fermentation
-doesnt require oxygen
recycle NADH back to NAD+
-
what are the three pathways which pyruvate can form energy generation
1)lactic acid
2)ehtanol + CO2
3)mixed acids + CO2 + H2
how can carbohydrates be oxidised or fermented
via aerobic or anaerobic respiration
what is the process of binary fission in bacteria
1)elongation of cell wall + start chromo duplication
2)septum wall grows inwards + chromos pulled towards opposite ends
3)septum synthesized = cell membrane separates cell chambers
what does Fts mean in regards to proteins
filamentous temperature sensitive proteins
what is the role of the Fts proteins during binary fission
interact to form the divisome
what is the divisome
cell division apparatus = forms septal ring and defines cell division plane
what is the role of Min proteins during binary fission
have bipolar gradient that helps to localise the ring
how are spores formed
formed from bacteria that cant survive in O2
