krebs cycle Flashcards
what are the two reduced co enzymes used in krebs cycle
NAD and FAD.
where does it take place
Mitochondrial matrix.
what are the products of the krebs cycle
6 reduced NADP
2 reduced FAD
2 ATP
4 CO2
what molecule is passed from the link reaction to the krebs cycle
2 Acetyl CoA (co-enzyme A) enters the krebs cycle from the link reaction.
what carbon compound is used to make acetyle coa to citrate
axaloacetate (4c) accepts acetyl (2c) from CoA, to create citrate (6c)
After Citrate (6C) is produced what is the next step.
citrate is dehydrogenated and decarboxylated to produce a five carbon. and produce products such as 2 Reduced NADH and 2 carbon dioxide
what does dehydrogenated mean
the removal of a hydrogen atoms from a substrate molecule
what does decarboxylation mean
removal of a carboxyl group from a substrate molecule
what is substrate level phosphorylation
the production of ATP from ADP and Pi
In the Krebs cycle, when does substrate level phosphorylation take place
When the first 4 carbon compound is created
what is the next step after the 5 carbon compound is produced
the 5 carbon compound is dehydrogenated and decarboxylated producing 2 carbon dioxide and 2 nadp. and producing a 4 carbon compound
what is the products of substrate level phosphorylation
2 atp
after substrate phosphorylation summarise the ending of the krebs cycle
another 4cc dehydrogenated producing 2 FAD
another 4cc is dehydrogenated to regenerate a molecule of a oxaloacetate again.
how is the krebs cycle aerobic, when no oxygen is directly used
because the krebs cycle wont take place if there is no oxygen present
