Question

during vigorous exercise, there may be insufficient oxygen available to completely break down pyruvic acid for energy. as a result, the pyruvic acid is converted to _______. stearic acid a strong base hydrochloric acid lactic acid

Explanation:

During vigorous exercise, when oxygen is insufficient, anaerobic respiration occurs. In anaerobic respiration in humans, pyruvic acid is converted to lactic acid. Stearic acid is a fatty acid. Hydrochloric acid is found in the stomach. A strong base is not a product of this metabolic pathway related to pyruvic acid breakdown under low - oxygen (during exercise) conditions.

Answer:

lactic acid
