  • Biochemistry: Liver Mitochondria Oxygen Uptake Inhibition

    Where's the site of inhibiiton: ATP synthase, malate dehydrogenase, Complex I, II, or III Isocitrate, 2-ketoglutarate and malate are substrates of Dehydrogenases in the Krebs cycle that produce NADH as one of the products of oxidation reactions.

  • Biochemical activity of Malate dehydrogenase

    It enters into the mitochondria via malate - succinate carrier and is oxidized to OAA by the action of the action of the intramitochondrail malate dehydrogenase. Here malate shuttle is reversible reaction and can function in either direction

  • Biochemistry - Describe the observed differences between the patient's and control mitochondria

    That means that the patient can convert succinate to fumarate, and fumarate to malate, and malate to oxaloacetate and oxaloacetate back into citrate. Therefore, we've pretty well narrowed down the location of the defect.

  • Net ATP Generation From 14CH3-COOH

    Since the single bond between the CH2 and the CH2 of succinate is freely rotatable and the entire molecule is symmetric, then the 14C label is now on both C2 and C3 of fumarate.

  • Experimental Design

    glutamate + malate are more inhibited than succinate; 3. both ions act on sites 1 and 2 of ATP synthesis; 4.

  • Oxaloacetate and oxygene consumption

    Therefore, addition of OAA or malate stimulates the oxidation of a much larger amount of acetyl-CoA as we mentioned in (a).

  • the steps of glycolysis

    SUCCINATE becomes FUMARATE in a process that converts one _FAD_ into _FADH2_ 7. FUMARATE becomes MALATE 8.

  • Electron Transport

    NADH and FADH2 that are produced by glycolysis, the citric acid cycle and fatty acid oxidation are oxidized by the respiratory electron-transport chain in the mitochondrion.

  • aerobic respiration of glucose

    Second, NAD+ malic enzyme is usually absent in animals but serves as an alternate pathway for oxidation of PEP in plants. 3.
