what are the basic 4 steps of beta oxidation
|
1) Oxidation
2) Hydration 3) Oxidation 4) thiolytic cleavage |
|
|
Step 1 process
|
the beta and alpha carbons become oxidized to form an alkene
|
|
|
Step 1 enzyme
|
Acyl CoA dehydrogenase
family of enzymes |
|
|
Step 1 produces
|
FADH2 from FADH
|
|
|
amount of ATP step 1
|
7 cycles X 1.5
|
|
|
how many ATP are taken away from total ATP generated
|
2 ATP
|
|
|
Step 2 basic process
|
the alkene gets hydrated so that there is an OH group on the Beta carbon
|
|
|
Step 2 enzyme
|
Enoyl CoA hydratase
|
|
|
Step 2 produces
|
nothing, but needs water
|
|
|
Step 2 ATP generated
|
none
|
|
|
Step 3 basic process
|
the OH on the beta carbon make a dbl bond O to form carboxyl group
|
|
|
Step 3 enzyme
|
Beta hydroxyacyl COA dehydrogenase
|
|
|
Step 3 produces
|
NADH from NADP +
|
|
|
Step 3 ATP produced
|
7 cycles X 2.5
|
|
|
Step 4 basic process
|
addition of CoA in between B and alpha carbons produces a fatty acid CoA - 2 carbons and an acetyl coa
|
|
|
Step 4 enzyme
|
Acyl Coa actyltransferase
thioloase requires CoA addition |
|
|
STep 4 ATp
|
7 cycles X 10
last cycle produces 2 acetyl +1 8 X 10 = 80 |
|
|
pyruvate carboxylase positive allosteric effector
|
Acetyl Coa
