krebs cycle Flashcards
what feeds into the krebs cycle from the link reaction
acetly COA
what then happens to acetly
coa is released
how is COA released
bond broken between acetyl COA and then recyceled back into the link reaction
what is formed after acetly
citrate
how is citrate formed
from acetly joining oxaloacetate compound
how many carbons are at acetyl
2
ow many carbons are at oxaloacetate
4
how many carbons are at citrate
6
why are there 6 carbons at citrate
becuase the 4 carbon compound of oxaloacetate and the 2 carbon compound of acetyl join to form 6 carbon compound citrate
what is added to citrate
nad
what does the addition of nad to citrate do
oxidasing citrate by nad uses dehydroganase so citrate is dehydrogenated to form a 5 carbon compound
what else happens to citrate
decarboxylated by decarboxylase - remove co2
what forms after citrate
5 carbon compound
what forms after the 5 carbon compound
4 carbon compound
what happens to 5 carbon compound
decarboxylated and dehydrogenated
what is added to 4 carbon compound
adp +pi
what happens to the adp
is phosphoralated to form atp
what happens to 4c
phophorilation of adp+pi to form atp
what else happens to 4 c compound
h+FAD is added and a pair of hydrogen atoms are removed and accepted by coenzyme FAD becoing reduced to FADH
what does the fad become
FADH
what happens to the fad added
it is reduced
when is FAD added
after the addition of adp on the 4 carbon compound
after fad is reduced what does this form
the same 4 carbon compound
what happens to this second 4 carbon compound
further dehydrogenated
