Detailed explanation-1: -At this point, muscle fibers can switch to a breakdown process that does not require oxygen. The process, called anaerobic gylcolysis (sometimes called anaerobic respiration) breaks down energy stores in the absence of oxygen to produce ATP.
Detailed explanation-2: -The production of energy used in muscle contraction takes place through the anaerobic way (without oxygen).
Detailed explanation-3: -When your body runs out of oxygen, or your other systems can’t deliver oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead.
Detailed explanation-4: -The presence of oxygen allows the muscle energy systems to produce the chemical ATP from the breakdown of glucose, providing the energy to carry out the muscle contraction. Glucose is obtained in the muscle cell from the breakdown of the chemical called glycogen.
