Question
There are characteristic changes in functional groups, one after another after another, in the beta-oxidation pathway. The same sequence of changes of functional groups occurs in the citric acid cycle. Look back at the citric acid cycle and find the 3 reactions that undergo the same functional group changes, in the same order, that occur in beta oxidation.
The possible answers (below) are given based on the reaction-numbers in the CAC
A. steps 1 through 3
B. steps 4 through 6
C. steps 6 through 8
D. steps 1 and then 4 and then 6
E. steps 5 through 7
Explanation / Answer
beta oxidation ; fatty acid degradation process ,
it is option A ,step1 through step 3
step 1 in beta oxidation = dehydrogenation process where transacylation of double bond between alpha and beta carbon transfered through FAD .
step 3 dehyrogenation of betahydroxy group to a ketone transferred to ketone .
