A high concentration of NADH would result in the inhibition of 11ea8d43_ab8d_e5b7_b445_37849298944f_TB6697_11_TB6697_11-ketoglutarate dehydrogenase. This is because high levels of NADH indicate that the cell has sufficient energy and does not need to generate more ATP via the citrate cycle. Therefore, inhibiting 11ea8d43_ab8d_e5b7_b445_37849298944f_TB6697_11_TB6697_11-ketoglutarate dehydrogenase prevents unnecessary ATP consumption.
