Oxidative Metabolism - CHO Flashcards
(42 cards)
do all 3 systems interact for all activities or just some
all
how many systems often dominate one task
one
when does cooperation between energy systems increase
during transition
what are the 3 stages to complete full oxidation of CHO
glycolysis, Krebs cycle, ETC
is the oxidative system aerobic or anaerobic
aerobic
how much ATP can 1 CHO make
glucose is 32/ glycogen is 33
how much ATP can 1 Free fatty acid make
over 100
what is the oxidative system duration like
a steady supply for hours
what is the most complex of the 3 bioenergetic systems
oxidative
where does the oxidative system occur
in the cells mitochondira
why is the arrangement randomized of mitochondria
- to be by capillaries
- too much O2 damages mitochondria cuz of reactant oxygen species
what does the kreb cycle complete
oxidation of substrates
what other things does the kreb cycle produce
NADH+H+
FADH2
GTP (goes to ATP)
how much pyruvate does 1 glucose molecule make
2, which means 2 acetyl coA and 2 times through the kreb cycle
what happens to energy production in oxidatio reduction reactions
energy production occurs with the transfer of an electron, either adding or removing the electron to a molecule.
oxidation def
removing electrons, getting more positive
reeduction def
adding electrons, getting more negative
NADH+H+ and NAD+
which is oxidized vs reduced
NADH+H+ is the reduced form
so
NAD+ is the oxide form
what is lost when pyruvate goes to acetyl coA
carbon
how is oxidative phosphorylation controled
a negative feedback looop with regulates the kreb cycel
RLE of kreb cycle
Isocitrate dehydrogenase
what does isocritrate dyehydrogenase do
acts like PFK does for flycolysis
regulates ETC
is inhibitd by ATP, but activated by ADP
what breaks down ATP
ATPase
to ADP and Pi
Production yield of Kreb Cycle
2 ATP, 6 NADH+H+ , 2 FADH2
