How is a “committed step” defined in the context of a metabolic pathway and why are they important? Which steps and/or enzymes are involved in the committed steps in the Krebs Cycle? What are the possible implications of these steps were deregulated?
In the presence of oxygen, the mitochondrion in yeast is used for aerobic respiration,however, under anaerobic conditions,the yeast mitochondria have been found to have other function. Identify and briefly discuss four of these functions
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?

- A glucose-fed yeast cell is moved from an aerobic environment to an anaerobic one. For the cell to continue to generate ATP at the same rate, approximately how much glucose must it consume in the anaerobic environment compared with the aerobic environment?arrow_forwardA genetic disease called glucose-6-phosphate dehydrogenase deficiency is inherited in a manner similar to that of sickle-cell anemia except that it occurs most frequently in males. The defective enzyme cannot keep erythrocytes supplied with sufficient amounts of the antioxidant molecule NADPH NADPH protects cell membranes and other cellular structures from oxidation. Describe in general terms the inheritance pattern of this molecular disease.
