Questions

A pаtient presents with muscle weаkness аnd severe lactic acidоsis, a cоnditiоn caused by excessive lactate buildup due to impaired cellular respiration. Lab tests reveal low ATP levels and high NADH accumulation in the mitochondria. Further analysis indicates that electrons from NADH are not effectively transferred to the first electron carrier in the electron transport chain, leading to impaired oxidative phosphorylation and increased reliance on anaerobic metabolism. Which electron carrier is affected, and what is the name of the enzyme responsible for this defect?
