alleryHow many CO₂ molecules are released per glucose by the link reaction plus Krebs cycle?
A2
B4
C6
D12
Answer & Solution
Correct answer: C. 6
From one glucose, the link reaction releases 2 CO₂ (1 per pyruvate × 2), and the Krebs cycle releases 4 CO₂ (2 per turn × 2 turns).
Total = 6 CO₂, matching the 6 carbons in glucose. No carbon is left over.
