During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid.

The dissociation of lactic acid to lactate is shown in the reaction. Lactic acid has a pKapKa of 3.86.3.86.

Lactate Lactic acid НО ОН +H + .

A solution containing a mixture of lactic acid and lactate was found to have a pH of 4.23.4.23. Calculate the ratio of the lactate concentration to the lactic acid concentration in this solution.

Lactate Lactic acid НО ОН +H + .

During high-intensity exercise such as sprinting or lifting a very heavy weight, energy is provided to cells by the phosphogen system (or ATP-PC system), which only works for a few seconds. If the diffusion constant of ATP is 3 ×10−10 m2 s-1, how far could this molecule diffuse in 5 seconds? (not 5.477E-5 m)
