New biosensors, applied like a temporary tattoo to the skin, can alert serious athletes that they are about to "hit the wall" and will find it difficult to continue exercising. these biosensors monitor lactate, a form of lactic acid, released in sweat during strenuous exercise. which of the statements below is the best explanation of why athletes would need to monitor lactate levels?

The answer to this question would be: During anaerobic respiration, lactate levels increase when muscles cells need more energy. However, muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

Lactate will be produced when the muscle cells doing anaerobic respiration. The lactate can be accumulated in the cells causing the muscle to be fatigue. Using the information from the tattoo the athlete can adjust their exercise intensity to prevent the accumulation.
