How many NADH+H+ and FADH2 molecules are produced in a single turn of TCA cycle?

There are three points in the TCA cycle where NAD+ is reduced to NADH+H+  ( During the conversion of Citric acid to α-keto glutaric acid, α-keto glutaric acid to succinyl co.A and conversion of Malic acid to Oxaloacetic acid) and one point where FAD+ is reduced to FADH2 during the formation of Fumaric acid from Succinic acid.
