Lactic acid is removed via conversion into four products. Which set lists these products?

• A. Urine, Sweat, Glycogen, CO2 + H2O
• B. Blood, Lymph, Hair, Skin
• C. Urine, Sweat, Water, Oxygen
• D. Sweat, Blood, Fat, Protein

Answer: (A)

When lactic acid is cleared from the body after intense exercise, it can be disposed of in several ways that together account for four outcomes. Some lactate is transported to tissues where it is oxidized to carbon dioxide and water, releasing energy. It can also be taken to the liver and converted back into glucose, which can then be stored as glycogen. A portion of lactate and hydrogen ions is excreted from the body via urine, and another portion is lost through sweat. So the four products listed are carbon dioxide and water, glycogen, urine, and sweat. The other options include items that aren’t produced or derived from lactic acid clearance, such as hair, skin, or fat, or components like oxygen, which aren’t products of the removal process.
