two purposes of the TCA cycle Flashcards
1
Q
- oxidize acetyl-coA to CO2 to produce
A
energy in the form of
- atp
- reducing power of NADH and FADH2
2
Q
(reduced coenzymes used by
A
electron transport chain and
oxidative phosphorylation to make ATP)
3
Q
the use of many steps in the oxidation of acetyl-coA to
A
CO2 enables conservation of most of the energy as work with little lost as heat.
4
Q
- supply precursors for biosynthesis of
A
carbs, lipids, amino acids, nucleotides and porphorins.
5
Q
intermediates of the cycle are starting points for many
A
biosynthetic reactions
6
Q
the cycle itself
A
is not a pathway for a net degradation of any cycle intermediates.
7
Q
cycle intermediates can be shared with
A
other pathways ,
8
Q
which may lead to re-supply or net
A
net decrease in cycle intermediates.
9
Q
TCA can slow down if
A
another reaction is using them
