Recall that beta-hydroxybutyrate is oxidized by the enzyme beta-hydroxybutyrate dehydrogenase withsimultaneous reduction of NAD+ to NADH. How might this affect the reduction potential at Complex I in theelectron transport chain? (Note: you will need to use the form of the Nernst equation that uses non-standardconditions.)

Acid phosphatases are an important group of enzymes that can be detected in human bloodserum. Under slightly acidic conditions (pH 5.0), this group of enzymes can hydrolyzebiological phosphate esters as follows:R-O-P-O3-2 + H2O -----> R-OH + HO-P-O3-2Acid phosphatases are produced and can be detected in erythrocytes, kidney, spleen, the liver,and prostrate gland. The enzyme from the prostrate gland is clinically important because anincreased activity in the blood is frequently an indication of cancer of the prostrate gland.Tartrate ion can strongly inhibit the phosphatase from the prostrate gland, but not acidphosphatases from other tissues. How can you use the information above to develop a specific procedure for measuring the activity of the acid phosphatase of the prostrate gland in humanblood serum?
