|
how are energy and biosynthetic intermediates used to support biosynthesis
|
intermediates are shunted off to other pathways to make a variety of products
|
|
|
is anabolism endergonic or exergonic
|
endergonic so needs NADPH and ATP to happen
|
|
|
catabolism usually releases energy that can be captured by the cell and used in _____
|
anabolism
|
|
|
what is respiration
|
a type of metabolism that uses an electorn trnasport system in the cfell membrane to create a proton gradient for ATP production
|
|
|
what is fermentation
|
a type of metabolism that is anaerobic and does not rely on the ETC for ATP
|
|
|
what does fermentation rely on
|
glycolysis, TCA, PPP, fermentation steps for energy generation and biosynth
|
|
|
what dose PPP stand for
|
pentose phsophate pathways
|
|
|
does fermentation yield higher or lower enenrgy compared to respiration
|
lower because O is not the final e acceptor
|
|
|
does fermentation imply a faster or slower growth rate and why
|
slower because o is not final e acceptor therefore a decrease in reduction potential
|
|
|
what is the overall reaction of glycolysis
|
glucose + 2 ADP + P + 2 NAD+ --> 2pyruvate + 2ATP + 2NADH
|
|
|
how many ATP are made in glycolysis
|
8 ATP
|
|
|
what are the important intermediates of glycolysis and where do they each go
|
G6P to PPP
F6P to PPP |
|
|
why is aerobic respiration indicative of a higher growth rate
|
increased reduction potential
|
|
|
what does fermentation involve
|
glycolysis
TCA PPP fermentation steps |
|
|
what is the goal of fermentation
|
energy for biosynthesis
|
|
|
does fermentation use ETC?
|
no
|
|
|
how many ATP are made in krebs cycle
|
30
|
|
|
what is the overall reaction of TCA
|
pyruvate + 4NAD+ + FAD+ + GDP
3CO2 + 4NaDH + FADH + GTP |
|
|
NADH = ___ ATP
|
3
|
|
|
FADH2 = ___ ATP
|
2
|
|
|
what are important intermediates of PPP
|
glyceraldehyde 3 P
fructose 6 P G3P pyruvate |
|
|
what is an aerobe
|
an organism that lives in teh presence of air that is not damage by oxygen
|
|
|
what is an anaerobe
|
organism that lives in the absence of air or oxygen and is usually damaged by o2
|
|
|
what is ATP produciton using the ETC
|
oxidative phosphorylation
|
|
|
what happens to O2 when it accepts the final electron
|
h2o
|
|
|
are there intermediates in the ETC
|
no its not a conversion. just a passing of e-.
|
|
|
why do you put ecoli on a shaker
|
to airate
|
