प्रश्न
Sometimes when we do heavy exercise, anaerobic respiration takes place in our muscle cells. What is produced during this process?
विकल्प
alcohol and lactic acid
alcohol and CO2
lactic acid and CO2
lactic acid only
उत्तर
lactic acid only
Explanation:
When we do heavy exercise our body does not get enough oxygen to produce the required energy. To get additional energy, anaerobic respiration occurs within our muscle cells. In this process, there occurs a partial breakdown of glucose to produce lactic acid. The accumulation of lactic acid in the body causes muscular cramps.
