Krebs Cycle
How many acetyl CoA molecules are formed from one glucose
2
How many pyruvic molecules are formed from one glucose?
2
what is the first reaction in the KC?
2C molecules of Acetyl CoA + 4C molecule of oxaloacetate= 6C molecule of citrate
Each turn of the Krebs Cycle produces ___ NADH ____ FADH from the four oxidation reduction reactions
3 NADH 1 FADH
How many NADH and FADH are produced from one glucose molecule
6 NADH 2 FADH
What is the first substrate in the krebs cycle
Acetyl CoA
What exact place does hydrogen have to be in the Kreb's cycle?
It must be present for the transfer of hydrogens in the form of NADH and FADH to the electron transport chain there O2 serves as the final hydrogen acceptor
(1 of 4 Oxidation-reduction-reactions) Isocitrate
is oxidized to alpha-ketoglutarate andn NAD is reduced to NADH
(3 of 4 Oxidation-reduction-reactions) Succinate
is oxidized to furmate and FAD is reduced to FADH
(4 of 4 Oxidation-reduction-reactions) Malate
is oxidized to oxaloacetate and NAD is reduced to NADH
(2 of 4 Oxidation-reduction-reactions) Alpha-ketoglutarate
is oxidized to succinyl CoA and NAD is reduced to NADH
What type of reaction starts the krebs cycle and how does it work
oxidation reduction reaction it begins with the pyruvic acid being oxidized to acetyl CoA and NAD being reduced to NADH
What is the primary purpose of the Krebs cycle in carbohydrate metabolism?
to compplete the oxidation (removal of hydrogen) of glucse using NAD and FAD electron carriers
Decarboxylation reactions
when 2 CO2 molecules are removed
