University work technique summative 02
The answer:
To create a diagram based on the information presented in the text "Understanding
Cellular Respiration: The Pathway from Glucose to ATP", we must outline the key steps
and stages of cellular respiration:
1. Glycolysis (occurs in the cytoplasm)
 Glucose → 2 Pyruvate + ATP + NADH
2. Transition Reaction (occurs in the mitochondria)
 Pyruvate → Acetyl-CoA
3. Krebs Cycle (also known as the citric acid cycle; occurs in the mitochondrial matrix)
 Acetyl-CoA → CO₂ + ATP + NADH + FADH₂
4. Electron Transport Chain (occurs in the inner mitochondrial membrane)
 NADH + FADH₂ → ATP (via oxidative phosphorylation)
 Oxygen (final electron acceptor) + Protons + Electrons → Water
