NADH produced in the glycolytic pathway cannot enter the mitochondrial membrane, so the shuttle systems are utilized to deliver the electrons to the ETC. Using a flowchart, illustrate and differentiate the flow of the electrons in the ETC when electrons from cytosolic NADH are delivered to the ETC via the two shuttle systems.
Leigh syndrome is characterized by psychomotor regression: that is, the progressive loss of mental andmovement abilities. Patients also suffer from lacticacidosis, a condition in which mitochondrial respiration is deficient, so their tissues metabolize glucoseanaerobically, leading to the buildup of lactate. Somepatients with Leigh syndrome have a mutation in themitochondrial gene MT-CO3, which encodes a subunit of the electron transport complex cytochromec oxidase. Other patients diagnosed with Leigh syndrome have a loss-of-function mutation in the nucleargene SURF1, which encodes a factor needed for theassembly of this same enzyme complex.a. How can the same symptoms result from mutationsin a mitochondrial gene and from mutations in anuclear gene?
