ETC and photosynthesis: legend for previous figure slide can disregard.
More ATP E.Coli with anaerobic respiration if no oxygen
Yeast: by product ethanol
can’t do fermentation
Nitrifying bacteria: use ammonia or nitrite as e source good for agriculture
Methanogens : produce methane two ways won’t use organic forms: h2 and co2=chemoautotrophs
Chemoheterotrophs use ch3cooh
Methanotrophs: use methane
In membrane: site of photosynthesis
Why? Goal is to build a pmf
O2 e ACCEPTOR h20 e DONOR
Cyanobacteria, algae: z formation
Cyclic photophosphorylation when reducing power is enough.
Cyanobacteria can also use sulfide as e source. can reduce Nad and Nadph
Cannot use h20 as e donor
Calvin Cycle: fix Carbon, incorporate CO2 as energy (USES, not make, ATP)
