Solution
The correct option is B Lactate
In a hurdle race, a person requires energy production at a much higher rate. In those cases, the working muscles generate energy anaerobically. This energy comes from glucose through a process called glycolysis in which glucose is broken down or metabolized into a substance called pyruvate through a series of steps. When oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown and thus energy production to continue. The working muscle cells can continue this type of anaerobic energy production at high rates for one to three minutes, during which lactate can accumulate to high levels.Hence the correct option is C.
