Chemoorganotrophs obtain energy by extracting electrons from chemicals and storing them as NADH.
|
The electrons can be converted into energy in the form of ATP by the glycolysis....in the form
1. fermentaton= a process by which electrons from NADH are donated to organic substrates 2. Aerobic respiration, in which e's and H+ enter an electron transport chain and are donated to Oxygen 3. Anerobic respiration, in which the e's and H+ enter an electron transport chain and are donated to an electron acceptor that is not oxygen. |

Examples of Aerobic and Anaerobic Respiration by Chemoorganotrophs
|
Aerobic
Electron Acceptor: Oxygen Reduced product: water Anaerobic Electron Acceptor: NO3-, SO4-, CO2 Reduced product: NO2-, N2O, N2, H2S, CH4 |
|
|
Examples of Aerobic and Anaerobic Respiration by Chemolithotrophs
|
Aerobic
Electron Donor: H2, NO2-, NH4+, Fe2+ Electron Acceptor: Oxygen Reduced product: water FOR ALL, NO3=, NO3-, Fe3+ Anaerobic Electron Donor: H2, S, H2S Electron Acceptor: NO3-, SO4-, Reduced product: NH2S, WATER, SO4 2-, N2 |

|
Phototrophs use the energy of sunglight to extract e's from Inorganic molecules (photolithotrophs) and organic molecules (photoorganotrophs)
|
True
|
|
|
Photosynthetic organisms include:
Plants and algae cynaobacteria |
electrons from water.
product is O2. |
|
|
Photosynthetic organisms include:
green sulfur bacteria purple sulfur bacteria purple non-sulfur bacteria |
Electrons from H2, H2S, S
No O2 is produced (anoxygenic) |
|
|
Advanced photosynthesis is invented by Cyanobacteria. it invented phtosyst II
|
O2 is created when H2O is splitted in the 1st photosystem. Electron from water is given to NADP to form NADPH.
