Although some citric acid cycle enzymes operate primarily in the mitochondria, malate dehydrogenase operates in both the cytosol and the mitochondria. Match each function to cytosolic malate dehydrogenase or mitochondrial malate dehydrogenase.

A. Cytosolic malate dehydrogenase

B. Mitochontrial malate dehydrogenase

1. transfers reducing equivalents from cytosolic NADH to a molecule that can tranverse the inner mitochondrial membrane

2. generates mitochontrial NADH from reducing equivalents that originate in the cytosol

3. reduces oxaloacetate to malate

4. oxidizes malate to oxaloacetate

5. reduces NAD+ to NADH

6. oxidezes NADH produced in glycosis to NAD+

7. catalyzes last reaction in citric acid cycle that regenrates oxaloacetate( ▲G = 29.7kJ/mol)

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
