|
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
|
|
|
As the cells run out of oxygen, they die off gradually and the weightlifter’s muscles have fewer contracting muscle cells.
|
|
|
The cells will never run out of oxygen if the weightlifter is breathing.
|
|
|
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.

Detailed explanation-1: -Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?-As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of •ATP in the absence of oxygen.
Detailed explanation-2: -Glycolysis. Glycolysis is the metabolic reaction which produces two molecules of ATP through the conversion of glucose into pyruvate, water, and NADH in the absence of oxygen. The glucose for glycolysis can be provided by the blood supply, but is more often converted from glycogen in the muscle fibers.
Detailed explanation-3: -ATP hydrolysis provides the energy needed for many essential processes in organisms and cells. These include intracellular signaling, DNA and RNA synthesis, Purinergic signaling, synaptic signaling, active transport, and muscle contraction.
