Open in App
Solution
The correct option is C Lactic acid
The type of fuel used during physical activity also depends on the efficiency with which oxygen is delivered to muscle cells. The complete breakdown of glucose occurs when O2 is present which is called as aerobic metabolism. When O2 is unavailable, glucose breakdown is incomplete and it results in the formation of lactic acid. Accumulation of lactic acid leads to sore muscles.
Incomplete breakdown of glucose does not result in the formation of alcohol, water or CO2.
Thus, the correct answer is option D.
