Congrats to Coug, Ms89, BioCF on those stratospheric scores!
Question about the level of memorization needed walking into the exam. Did you have FA nearly rote memorized? Or did you have it mostly memorized? As I go through practice question banks, I'm finding I can often pick the right answer even though I don't know that piece of info in FA 100%. For example, for a question like:
In 5 yr old girl w/ abdominal pain, acts erratically, in an old house being remodeled, which enzyme is most likely not functioning properly.
A: aminolevulinic acid dehydratase
B: adenosine deaminase
C: glucose-6-phosphatase
D: porphobilinogen deaminase
E: sphingomyelinase
Obviously the girl has lead poisoning. If you were to ask me which enzyme is inhibited by lead, I wouldn't be able to tell you off the top of my head. But given the answer options, I can then recall aminolevulinic acid...I'd be tempted by prophobilinogen deaminase. But, I would select (A) with certainty.
So my question is did you:
(A) Rote memorize the whole heme pathway as listed in FA (ex: FA 2013,pg 358, FA 2014,pg 388), including hydroxymethylbilane, which has no clinical correlate (but is written out in FA).
(B) Rote memorize just the 5 enzymes listed in the diagram and the 5 diseases associated with each one.
(C) Did not rote memorize the whole pathway nor the 5 enzymes nor the 5 diseases (ex: if I asked you on the morning of your exam which enzyme is affected in acute intermittent porphyria, you wouldn't be able to answer 'Porphobilinogen deaminase'). Instead, over the course of reading/re-reading FA and doing 2 question banks, you were familiar enough to recall the info when prompted. You might confuse 'porphobilinogen deaminase' & 'uroporphyrinogen decarboxalyse' as causative for Porphyria cutanea tarda....but since they typically don't put those two answer choice together...you'd pick Uropor. decarb.
