krebs cycle

Question 1

what feeds into the krebs cycle from the link reaction

Answer 1

acetly COA

Question 2

what then happens to acetly

Answer 2

coa is released

Question 3

how is COA released

Answer 3

bond broken between acetyl COA and then recyceled back into the link reaction

Question 4

what is formed after acetly

Answer 4

citrate

Question 5

how is citrate formed

Answer 5

from acetly joining oxaloacetate compound

Question 6

how many carbons are at acetyl

Answer 6

2

Question 7

ow many carbons are at oxaloacetate

Answer 7

4

Question 8

how many carbons are at citrate

Answer 8

6

Question 9

why are there 6 carbons at citrate

Answer 9

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

Question 10

what is added to citrate

Answer 10

nad

Question 11

what does the addition of nad to citrate do

Answer 11

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

Question 12

what else happens to citrate

Answer 12

decarboxylated by decarboxylase - remove co2

Question 13

what forms after citrate

Answer 13

5 carbon compound

Question 14

what forms after the 5 carbon compound

Answer 14

4 carbon compound

Question 15

what happens to 5 carbon compound

Answer 15

decarboxylated and dehydrogenated

Question 16

what is added to 4 carbon compound

Answer 16

adp +pi

Question 17

what happens to the adp

Answer 17

is phosphoralated to form atp

Question 18

what happens to 4c

Answer 18

phophorilation of adp+pi to form atp

Question 19

what else happens to 4 c compound

Answer 19

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

Question 20

what does the fad become

Answer 20

FADH

Question 21

what happens to the fad added

Answer 21

it is reduced

Question 22

when is FAD added

Answer 22

after the addition of adp on the 4 carbon compound

Question 23

after fad is reduced what does this form

Answer 23

the same 4 carbon compound

Question 24

what happens to this second 4 carbon compound

Answer 24

further dehydrogenated

Question 25

what is added to the second 4 carbon compound

Answer 25

h+nad

Question 26

what happens to the nad

Answer 26

gets reduced to nadh

Question 27

what happens aafter dehydrogenation

Answer 27

regenerates oxalocetate and the cycle starts again

Question 28

how is oxaloacetate produced form 4 carbon compound

Answer 28

4 carbon compound is dehydrogenated
