20. Which one of the following is an effect of lactic acid?
A) gives feeling of excitement
B) causes extreme hunger pain
C) helps to create oxygen in the lungs

Answer 1

Answer:

The body makes lactic acid when it is low in the oxygen it needs to convert glucose into energy. Lactic acid buildup can result in muscle pain, cramps, and muscular fatigue. These symptoms are typical during strenuous exercise and are not usually anything to worry about as the liver breaks down any excess lactate.
