lactic acid fermentation
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
If the demand for oxygen is not met for a long period of time, the cells within the muscle tissue will die.
Myoglobin
The process in muscles which uses oxygen is called respiration. Muscles, like all aerobic living cells, require oxygen for aerobic respiration, which is the process by which cells convert food into energy. So when muscles contract, they are using oxygen. When muscles do not get sufficient oxygen for contraction, problems arise. The muscle cells must use anaerobic repiration which is respiration without oxygen. They cannot do this for very long though as the byproduct of anaerobic respiration is lactic acid which causes a fall in pH.
Oxygen and carbon dioxide are two substances exchanged across the membranes of red blood cells and muscle cells during respiration. Oxygen is taken up by red blood cells in the lungs and delivered to muscle cells for energy production, while carbon dioxide produced by muscle cells is carried away by red blood cells to be exhaled from the body.
It must be able to continue aerobic metabolism when skeletal muscle cannot
In the absence of oxygen after glycolysis, muscle cells will produce lactic acid through the process of fermentation. This allows the cells to regenerate NAD+ needed for glycolysis to continue in the absence of oxygen.
Fermentation is a way to produce energy when there isn't enough oxygen available.
Myoglobin-myoglobin stores oxygen from red blood cells, which are red. The reason myoglobin stores oxygen (if you wanna know) is to have it available when there's muscle activity.
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
When muscle cells are oxygen deprived, the heart must work harder to deliver enough oxygenated blood to the tissues. It may increase heart rate or contractility to compensate for the decreased oxygen supply. If oxygen deprivation persists, it can lead to tissue damage or even a heart attack.
During exercise muscle cells use oxygen.
In oxygen deprivation, muscle cells convert pyruvate into lactate through anaerobic glycolysis. This conversion allows the cells to regenerate NAD+ from NADH, enabling glycolysis to continue and produce ATP without oxygen. This helps sustain energy production in the absence of sufficient oxygen supply.
All cells need Oxygen.
If the demand for oxygen is not met for a long period of time, the cells within the muscle tissue will die.
When the muscle cells are deprived of oxygen, the cells produce ATP through the anaerobic fermentation. Glycolysis occurs in the cytoplasm and does not need oxygen. In the glycolysis pathway, two ATPs are produced as net products. Also, anaerobic fermentation occurs. The pyuvate is converted into lactic acid and regnerate NAD using this process.
