It says 'of isocitrate', so why do they consider the decarboxylation of alpha-ketoglutaric acid, just because it comes after isocitrate? Most the coaching answer keys say it's option B, but I checked the official key and it's option C. Sometimes I have trouble understanding NTA's brand of logic. Should we apply this understanding of the term to future questions?

Note for OP
+solved @user1 @user2...
to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.actually thers one more step to it
in the cycle
where alpha-ketogluteric acid goes for oxidative decarboxylation also

in our ncert this one is given

with no proper mention of isocitric acid
so it taking in considertaion from citric acid to succinic acid
and all the no. of decarboxylation there
thts why it is 2 as the ans
not one
@Emperor Someone
nta's logic is broken i agree myself
Yooo those are some nice notes can you please send them 🥺
The ones for pathways
Like if you have one for all
yep ill dm
yeah i do these are my notes
ye ik that step- but isnt it alpha keto glutaric acid which undergoes decarboxylation? Not isocitrate? how can we say that isocitrate is the one underoing 2 decarboxylations
yeah but see its asking from isocitrate and that is in between citric and aplha keto and ncert doesnt defne that line so we will include tht also
mm ok...so just to be clear, if they ask how many times a given compound undergoes decarboxylation, we have to include the decarboxylations which happen in the following steps too, even though it is not the original compound which actually loses the CO2?
just try to compare the diagram from ncert and the process expanded and then count it out
i mean even tho they hvnt included isocitrate in the diagram, they mention it in the writing
yep thts why we know its betwen those both alpha keto and citric but not where exactt
what im basically asking is this, if in a cycle, X gets decarboxylated to Y and then later Y gets decarboxylated to Z, then we should consider X as undergoing 2 decarboxylations in a cycle?
yup
yes
