You are a hyper neuro-optimized BMC Biochemistry medical tutor who gets 100% on al bmc mcqs exams and i have few days left before BMC exam.Generate ALL most high yield MCQs from each page/slide starting from slide 4(skip objectives) for my BATTERJEE MEDICAL COLLEGE EXAMS. Each MCQ should contain picture or authentic diagram explaining it.Tell me for each slide MCQs, in which BMC past year they appeared . Then in end generate high yield summary cheatsheet and give ALL bmc tips

🎯 FINAL EXAM-DAY RAPID-FIRE REVIEW

Here's what to nail in the last 30 minutes before your BMC exam:
The 5 Numbers You Must Know:
Palmitate = 129 ATP
Palmitate synthesis = 8 acetyl-CoA + 14 NADPH + 7 ATP
Per beta-ox cycle = 5 ATP (2+3)
Fat = 9 kcal/g; Carbs/Protein = 4 kcal/g
Palmitate = 16 carbons, 7 cycles, 8 acetyl-CoA
The #1 Trap: Phosphorylation Rule
Enzyme	Active form	Trigger
ACC (synthesis)	DE-phosphorylated	Insulin
HSL (lipolysis)	PHOSPHORYLATED	Glucagon/Epi
The 3 Peroxisomal Diseases:
Zellweger = no peroxisomes → ↑VLCFA
X-ALD = ABCD1 defect, X-linked → ↑VLCFA + adrenal failure
Refsum = alpha-oxidation defect → ↑phytanic acid + neurologic
The "ONLY IN LIVER" fact: Glycerokinase only in LIVER (not adipose). Adipose must use glycolysis for glycerol-3-P.
The metabolic switch: Malonyl-CoA = inhibitor of CPT-I = the bridge preventing simultaneous FA synthesis + oxidation.
Good luck on your BMC exam! You've got this. 🏆 These 38 MCQs cover every testable concept from both lectures based directly on Dr. Abdulghany's slides. The ⭐⭐⭐⭐ items are the ones that have historically appeared in the most BMC past papers - prioritize those if time is short.
