ch 6 Flashcards
(34 cards)
energy currency (2)
NADPH/ NADH
heterotroph feeder pathway
one central pathway for carbon (one source for both)
autotrophs feeder pathway
different feeder pathway for carbon and energy source
microbes use energy for
growth and maintenance
Mechanisms ATP synthesis
Substrate- level phosphorylation, Transmembrane Ion Gradients
building blocks
amino acids, nucleotides, sugars, lipids
Macromolecules
proteins, nucleic acid, lipids, polysaccharides
feeder pathways
to assimilate UHHHH into central pathways
central pathways
glycolysis, TCA cycle, pentose phosphate
ATP synthesis reactions (2)
substrate levle phosphorylation, transmembrane ion gradient
substrate levels phosphorylation ex
fermentation, glycolysis TCA
types of trans ion gradients
Respiration - oxi phosphorylation
photosynthesis- photophosphorylation
fermentation occurs in
cytoplasm
auxiliary fueling pathways
alternate fueling pathway, recycling extra shit
transmembrane ion gradients makes
hella energy produced, makes ATP and water, ADP to ATP
transmembrane ion gradients location
pro cell membrane, euk mitochondria membrane
ATP synthase
uses the gradient to energize the
phosphorylation of ADP and make ATP
ion gradients are used for
active transport, maintain water pressure, power flagella, maintain ph of cell
Respiration uses the
electron transfer system
electron transfer system
transfer e between donors and acceptors
terminal election acceptor
aerobic- oxygen
anaerobic- ignorganic or oxygen
best electron acceptor
O
chemoautotrophs
fix co2 to make precursors, can and aerobic or anaerobic
photophosphorylation
proton motive force to make ATP synthase using light energy, needs hella energy
