Sports physiologists at an Olympic training center wanted to monitor athletes to determine at what point their muscles were functioning anaerobically. They could do this by checking for the buildup of which molecule?
They could do this by checking for the buildup of-
Lactic Acid molecule.
Respiration takes place in muscle cells depending on the availability of oxygen. In normal conditions when oxygen is available in sufficient amount then aerobic respiration takes place to support the need of energy. Here glucose is broken down to pyruvate which enters Kreb's cycle and then via electron transport chain energy in form of ATP is produced.
When the demand of oxygen in the muscles exceed the body's body's ability to deliver it then anaerobic respiration takes place. With insufficient oxygen, the muscle cells breakdown glucose very inefficiently and produce Lactic acid as the by product without entering kreb's cycle.
This lactic acid accumulates in the muscles causing painful muscle sores.
