๐ŸŽฏ Exam Strategy

Guaranteed Marks Plan

How to approach each part of the Biochemistry exam for maximum marks.

Part A
25 MCQs ร— 1 = 25 marks
Target: 20โ€“23 / 25
  • Peptide bond formation & protein levels of structure 8/8
  • Michaelis-Menten equation โ€” Km and Vmax meaning 8/8
  • Glycolysis โ€” net ATP yield & key enzymes 8/8
  • Types of enzyme inhibition (competitive vs non-competitive) 7/8
  • Reducing vs non-reducing sugars (Benedict's test) 7/8
  • Krebs cycle โ€” net output (ATP, NADH, FADHโ‚‚, COโ‚‚) 7/8
  • ฮฒ-oxidation โ€” activation of fatty acids & yield calculation 6/8
  • DNA vs RNA structural differences 6/8
  • Fat-soluble vs water-soluble vitamins (deficiency diseases) 6/8
  • Urea cycle โ€” starting substrate & key enzymes 5/8
Part B
5 Questions ร— 8 = 40 marks
Target: 32โ€“40 / 40
QUnitExpected Topic
21U1Protein structure (Primary โ†’ Quaternary) + Amino acid classification ๐Ÿ”ฅ
22U2Michaelis-Menten kinetics + Lineweaver-Burk plot ๐Ÿ”ฅ
23U3Glycolysis pathway โ€” all 10 steps with enzymes & ATP tally ๐Ÿ”ฅ
24U3/U4Krebs Cycle OR ฮฒ-oxidation of palmitic acid with ATP calculation
25U4/U5Urea Cycle OR DNA replication/transcription steps
Part C
1 Question ร— 10 = 10 marks
Target: 8โ€“10 / 10

Choose 1 of 2 questions. Typical options:

Q.26
Complete Glycolysis + Krebs Cycle + ETC โ€” integrated energy story ๐Ÿ”ฅ OR Enzyme kinetics โ€” Km, Vmax, all types of inhibition with graphs
Q.27
ฮฒ-oxidation of a specific fatty acid + total ATP calculation ๐Ÿ”ฅ OR Protein structure โ€” all four levels with examples + denaturation
๐Ÿ’ก Biochemistry Exam Secret: Draw pathway diagrams for full marks โ€” examiners love labelled arrows. For ATP calculations, always show the workings: NADH ร— 2.5 + FADHโ‚‚ ร— 1.5 + substrate-level ATP. A neat table of inputs/outputs from each stage scores maximum marks.
