cellular respiration in germinating peas Flashcards
glycolysis is the process from
1 glucose turns to = 2 “NADH, 2 “ATP”
Acetyl-CoA synthesis and Krebs Cycle
2 Pyruvate turns to = 8 NADH, 2 FADH, 2 ATP
Electron-Transport Chain
10 NADH, 2 FADH turns to = 32 ATP
the pyruvate synthesized during what?
glycolysis
what does pyruvate convert to?
acetyl-CoA
how does pyruvate convert to acetyl-CoA?
in the presence of oxygen, once acetyl enters mitochondria, it converts
what extra is created in the conversion of pyruvate to acetyl-CoA?
one molecule of carbon dioxide & one molecule of NADH
acetyl-CoA is metabolized through what SIX REACTIONS
Krebs Cycle or Citric Acid Cycle
Krebs Cycle or?
Citric Acid Cycle
Citric Acid Cycle or?
Krebs Cycle
each molecule of acetyl-CoA is metabolized to produce what?
2 molecules of CO2, some ATP, electrons
what are the extra “Kreb’s Cycle” electrons used for?
they are transfered to yeild reduced forms) NADH and FADH
what are the “reduced” electron-carrier molecules?
NADH & FADH2
what does the electron-transport chain synthesize?
ATP
what is the electron transport chain?
its a membrain-ey protein chain that collects electrons and hydrogen. The transporters switch between “reduced” and “oxidized” forms within the cell.
what are the “oxydised” electron molecules
NAD+ & FAD
the transporting of the electrons through the transport train creates extra energy used to-
-put hydrogen ions into the membrane of the mitochondria
hydrogen accumulating into membrane creates what?
an ion gradient, creating electrochemical imbalance across the membrane
what is the electrochemical imbalance used to create?
ATP
what is ATP synthase?
a membrane chain that gets activated by hydrogen flow, this makes a part of it spin and drive ATP production
what does each glucose molecule produce?
approx. 38 ATP
what does the electro-transport chain produce for each pyruvate
16 ATP
what does the electro-transport chain need to produce 16 ATP
a pyruvate molecule
Avogadro’s law?
At constant temperature
and pressure, 1 mole of any gas has the
same volume as 1 mole of any other gas.
