, Module 1: Cellular Respiration Overview & ATP
Energetics
Cellular Respiration is the universal process by which organisms convert biochemical
energy from nutrients into Adenosine Triphosphate (ATP), discarding metabolic
waste products. The overarching chemical formula is perfectly standardized worldwide:
C₆H₁₂O₆ + 6O₂ ⟶ 6CO₂ + 6H₂O + Free Energy (~32-34 ATP)
1.1 The Architecture of the Powerhouse: The Mitochondrion
To optimize points on open-ended international exam prompts, you must explicitly align
structure to function. The mitochondrion uses distinct compartmentalization:

Module 2: The Four High-Yield Biochemical Stages
Stage 1: Glycolysis (The Universal Ancient Pathway)
• Location: Cytoplasm (Does NOT require Oxygen; Anaerobic).
• Core Split: 1 Glucose (6-Carbon moleculue) is cleaved systematically into 2 Pyruvate
(3-Carbon molecules).
• Net Yield: +2 Net ATP (Uses 2 ATP in investment phase, synthesizes 4 ATP via
Substrate-Level Phosphorylation) and +2 NADH.
⚠️EXAM TRAP SIGNPOST:
International examiners frequently trick students regarding the net vs. gross yield of
Glycolysis. Gross production is 4 ATP, but because the Energy Investment phase consumes 2
ATP, the net payout is ALWAYS 2 ATP. Do not lose this easy mark!
