Draw a diagram of the electrochemical cell, labeling all electrodes and solutions. What is the pH in the Pt | H+ | H2 half-cell. What is the value of the equilibrium constant for the reaction occurring in this cell
The half life of pyruvic acid in the presence of an aminotransferase enzyme (which converts it to alanine) was found to be 221 s. How long will it take for the concentration of pyruvic acid to fall to 1/69 of its initial value in this first order ..
In the electron transport chain, electrons from FADH2 are eventually used to reduce O2 into H2O. Experimentally, the proton motive force created by this process will generate 2 ATP molecules from ADP and Pi, using ATP synthase.
