Q

why are there 6 carbons at citrate

A

becuase the 4 carbon compound of oxaloacetate and the 2 carbon compound of acetyl join to form 6 carbon compound citrate

11
Q

what does the addition of nad to citrate do

A

oxidasing citrate by nad uses dehydroganase so citrate is dehydrogenated to form a 5 carbon compound

16
Q

what is added to 4 carbon compound

A

adp +pi

17
Q

what happens to the adp

A

is phosphoralated to form atp

18
Q

what happens to 4c

A

phophorilation of adp+pi to form atp

19
Q

what else happens to 4 c compound

A

h+FAD is added and a pair of hydrogen atoms are removed and accepted by coenzyme FAD becoing reduced to FADH

20
Q

what does the fad become

A

FADH

21
Q

what happens to the fad added

A

it is reduced

22
Q

when is FAD added

A

after the addition of adp on the 4 carbon compound

23
Q

after fad is reduced what does this form

A

the same 4 carbon compound

24
Q

what happens to this second 4 carbon compound

A

further dehydrogenated

25
Q

what is added to the second 4 carbon compound

A

h+nad

26
Q

what happens to the nad

A

gets reduced to nadh

27
Q

what happens aafter dehydrogenation

A

regenerates oxalocetate and the cycle starts again

28
Q

how is oxaloacetate produced form 4 carbon compound

A

4 carbon compound is dehydrogenated
