Studies on human aging have shown that the levels of coenzyme Q10 (ubiquinone), measured in tissues such as heart muscle, are significantly lower in individuals over 70 years old than in younger individuals. This lower level is associated with significantly reduced contractile force of their heart muscle. Which is the most likely explanation for the reduced heart muscle function in these older individuals? Coenzyme Q10 is an uncoupling protein found in mitochondria; lower levels of it will result in less efficient mitochondria. Coenzyme Q10 is used to convert pyruvate to acetyl CoA; lower levels of it will result in a less efficient citric acid cycle, which will slow down the production of ATP. Coenzyme Q10 is an electron carrier in the electron transport chain in mitochondria; lower levels of it will result in less ATP being made by mitochondria during cellular respiration. Coenzyme Q10 is a lipid found in brown fat; brown fat is a major source of energy for all tissues in the body. Coenzyme Q10 is used in cleaving a 6-carbon sugar into two 3-carbon sugars during glycolysis; lower levels of it will result in lower amounts of ATP being produced.

Consider a gene in the mitochondrial genome that codes for a channel protein in the inner membrane that allows magnesium ions to travel freely across. If a mutation in that gene resulted in this protein allowing H+ to pass through it rather than magnesium, what would be the consequence for cellular respiration?
Anaerobic glycolysis of glucose potentially produces a fewer number of ATPs per glucose moleculein red blood cells than in muscle cells, because -Red blood cells contain bisphosphoglycerate mutase -Red blood cells lack phosphoglycerate kinase -Red blood cells do not have mitochondria -Red blood cells do not have a nucleus Which of the following is likely to be correct if all mutases are completely inhibited? -Removal of glucosyl residues from nonreducing ends of glycogen in the liver is compromised;therefore, release of free glucose into blood from the liver would decrease -Glycerol can be efficiently converted into glucose but cannot be efficiently converted into glucosylresidues in glycogen in the liver -Both A and B -Neither A nor B

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?
Cyanide is a rapidly acting, potentially deadly chemical that can exist in various forms.
