How many reduced dinucleotides would be produced with four turns of the citric acid cycle?
a) 1 fad and 4 nad+
b) 4 fad+ and 12 nad+
c) 2 fadh2 and 8 nadh
d) 1 fadh2 and 4 nadh
e) 4 fadh2 and 12 nadh

The reduced dinucleotides that would be produced with four turns of the citric acid cycle is E (4 FADH2 and 12 NADH)

Explanation:Each turn of the cycle forms one ATP as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell. Therefore four turns of the citric acid cycle will generate 4 FADH2 and 12 NADH
