How much ATP would be generated by having one molecule of oxaloacetate being completely oxidized to CO2 by oxidative phosphorylation? Assume all necessary intermediates and electron carriers are present to carry out the reactions.
in which of the reactions in the electron transport chain, coenzyme Q transfers electrons to complex 3 . Which molecule is reduced and which is oxidized in this reaction?
In the early days of “mitochondriology,” P/O ratios were determined from measurements of volume of O2 taken up by respiring mitochondria and chemical assays for disappearance of inorganic phosphate. Now, however, it is possible to measure P/O ratios simply with a recording oxygen electrode. How might this be done?
State whether the following statements are True or False, If False, explain why 5.1 Oxaloacetate is formed by the oxidation of L-malate 5.2 An overstimulation of the citric acid cycle will cause an overproduction of oxygen 5.3 The citric acid cycle occurs in the mitochondrial matrix of prokaryotes and eukaryotic 5.4 NADH and ADP are high energy electron carriers which can be utilised in the electron transport chain
Give all the reactions that will produce ATP either by substrate-level phosphorylation (SLP) or by oxidative phosphorylation (OP). If the given require a shuttle system, please indicate both MA shuttle and GP shuttle and give the ATP produced. Given: fructose 6-phosphate to 2pyruvate
The four complexes of the electron transport chain use the energy of electrons stored in reducing agents to create a concentration gradient of protons (H*) across the mitochondrial inner membrane. Give the number of protons pumped into the intermembrane space by each of the four complexes: complex I: complex II: complex III: complex IV:
Nicotinamide nucleotide transhydrogenase (NNT) in the inner mitochondrialmembrane catalyzes the reaction NADH + NADP+ → NAD+ + NADPH to generate the NADPH needed for certain reactions that help destroy reactive oxygen species. (a) Explain why the NNT reaction cannot be driven primarily by the diff erence in substrate reduction potentials (Δℰ). (b) In fact, the NNT reaction is driven by proton translocation across the membrane (from outside to inside). How does operation of the transhydrogenase aff ect the effi ciency of oxidative phosphorylation?
Calculate the ATP yield for the complete oxidation of the ketone body 3-hydroxybutryate to 4 CO2 in the mitochondrial matrix. Use P:O ratios of 2.5 for NADH and 1.5 for QH2. Draw the chemical reaction and the movement of electrons (including the enolate intermediate) necessary for the spontaneous decarboxylation of acetoacetate to acetone and CO2. (Hint: review the mechanism of step 4 in glycolysis and step 3 in the citric acid cycle). Why is acetoacetate undergoing spontaneous decarboxylation while 3-hydroxybutyrate does not?
For Krebs Cycle(Citric Acid Cycle) what are steps of cellular respiration for both aerobic (oxygen present) and anaerobic (without oxygen) respiration. what are the Inputs and Outputs: Clearly indicate the key substrates, intermediates, and products at each stage. Location: Show where this stage of cellular respiration occurs within the cell (e.g., cytoplasm, mitochondria). Energy Production: Highlight the ATP and NADH production at this stage. Oxygen: Show where oxygen is used in the process (e.g., ETC) and where carbon dioxide is produced. Electron Carriers: Indicate the role of electron carriers such as NAD+ and FAD in transferring eleDiagrams: Use diagrams or icons to represent the structures and molecules involved, such as the mitochondria, glucose, ATP, and oxygen. Key Information like important facts or formulas relevant to cellular respiration, like the chemical equations for each stage.
a newly identified bacterium called Nomore biochem is unable to synthesize ubiquinone. A mobile electron carrier called CXC3 is used as a substitute. From the information provided in the table, calculate delta G' and Keq value at 298K for the redox reaction that occurs in the Nomore Biochem electron transport chain.
