Term
| How are proteins catabolized? |
|
Definition
- Hydrolyzed by proteases into polypeptides and amino acids
|
|
|
Term
| ONCE proteins are hydrolyzed into polypep and AA, what happens? |
|
Definition
- Amino Acids undergo demamination to produce pyruate molecules.
|
|
|
Term
| Once Amino Acids undergo demamination to produce pyruate molecules what happens? |
|
Definition
| Pyruvate can enter the transition step, then proceed to the TCA |
|
|
Term
| Terminal electron acceptor of ATP prod. in chemolithoautotrophs |
|
Definition
- Most often O2 but can also be SO42- or NO3- or H2
- The last three substances are alternative substrates
|
|
|
Term
| ATP production in chemolithoautotrophs |
|
Definition
- Electrons for ETC are obtained from inorganic compounds instead of organics
|
|
|
Term
| Comparison of Chemolitho to Chemoauto |
|
Definition
- Much less NADH produced by Chemolitho
- Much less ATP producedby ChemolithO
- Takes much longer time to generate enough Proton Motive force to drive ATP synthesis and much longer generation times than chemoorganotrophs
|

Term
|
Definition
- H2 gas oxidizers
- Nitrifying bacteria
- Sulfur oxidizers
|

|
Term
| ATP production in photoautotrophs |
|
Definition
- Produced during light-dependent reaction of photosynthesis
|
|
|
Term

|
|
Definition
- Biosynthesis (or carbon fixation) occurs during the light-independent reactions
- The light independent- dark reactions
|
|

Term
| Cyanobacterial Photosynthesis 1: |
|
Definition
| Have 2 photosystems like eukaryotes: cyclic and noncyclic=ETC |
|
|
Term
| Cyanobacterial Photosynthesis 2: |
|
Definition
- Initial electrons come from chlorophyll a molecules excited by light
|
|
|
Term
| Cyanobacterial Photosynthesis 3 |
|
Definition
| PMF+ATP synthase=photophosphorylation of ADP--> ATP |
|
|
Term

|
Definition
| H20 used as terminal electron acceptor= oxygenic photophosporylation |
|
|
Term
| Anoxygenic photosynthesis |
|
Definition
| Purple and green bacteria |
