You need to know that you produce 3 NADH, 1 FADH2, and 1 GTP per cycle and if they were to name an intermediate like citric acid or acetyl-CoA, you can associate it with the kreb cycle. Other than that and that its in the mitochrondia, you do not need to know anymore information....
All other info will be provided on the exam with a diagram or something like it.
