Assumptions
•
Counted per acetyl-CoA, one turn: 3 NADH, 1 FADH₂, 1 GTP and 2 CO₂; a glucose gives two turns.
•
The cycle starts with acetyl-CoA (2C) joining oxaloacetate (4C) and ends by making oxaloacetate again.
•
Each card draws the carbons as dots and CoA as a tag, with what the step makes beside it.
