Microorganisms must do these types of work:
explain? |
Chemical-
synthesis of complex molecules transport- take up nutrients mechanical work- cell motility movement of structures w/in cell |
|
|
Roles of catabolism
|
fueling rxns
energy conserving rxns provide ready source of reducing power (electrons) generate precursors for biosynthesis |
|
|
Roles of anabolism
|
synthesis of complex organic molec from simpler ones
requires energy from fueling rxns |
|
|
If free energy change (change G) is negative the rxn is....aka.....
|
spontaneous
exergonic |
|
|
If free energy change is positive the rxn is.....aka....
|
non-spontaneous
endergonic |
|
|
Role of ATP in metabolism?
|
Exergonic breakdown of ATP is coupled with endergonic rxns to make them more favorable
|
|
|
Aerobic Respiration
substrates? end products? intermediate & final electron acceptors? Energy yield? |
glucose
H2O, CO2, ATP Intermediate-NAD+, FADH Final-O2 36-38ATP |
|
|
Fermentation
Substrates? Intermediate/Final Electron Acceptors Energy Yield |
Glucose
Intermediate- NAD+ Final-Endogenous Organic Compound Less than Aer or Anaer respiration |
|
|
Anaerobic Respiration
Substrates? Intermediate/Final Electron Acceptors Energy Yield |
Glucose
Intermediate-org substance Final-reduced org substance Egy yield-more than ferm less than aerobic |
