Catabolism Flashcards
Catabolism is
degrative, energy yielding
Anabolism is
Biosynthetic, energy using
What types of work must microbes do?
Chemical, Transport, Mechanical
What is the First law of thermodynamics?
Energy can be neither created nor destroyed
What is the second law of thermodynamics
Physical and chemical processes proceed towards an increase in entropy
Gibbs free energy needs to be - or + for a reaction to be spontaneous
Negative
what is ∆G for a catabolic reaction
Negative
what is ∆G for a anabolic reaction
Positive
2 Reasons ATP carriers a lot of energy
Phosphoanhydride bonds have a lot of repulsion and the products (ADP + Pi) are more soluble
Chemolithoautotroph energy, electron and carbon source
energy : Inorganic, Electron: Inorganic, Carbon Source: CO2
3 Common factors of fueling reactions
ATP as a short term energy carrier, Reducing power to supply electrons, precursor metabolites for biosynthesis
Net products of Acetyl-Coa synthesis and krebs per glucose
8NADH, 2 FADH2, 2 ATP or GTP
What is nitrification?
oxidation of ammonia to nitrate
what is nitrogen’s most reduced state
N2
What is reverse electron flow?
Using the proton motive force to reduce NADP to NADPH the use that for anabolism
