What else can I help you with?
In order for the muscle fatigue to end the muscle cells must be provided with what?
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
Does muscle tissue produce red blood cells?
No, muscle tissue doesn't produce any blood cells.
What happens in your muscle tissue and cells when the demand of oxygen is not met?
If the demand for oxygen is not met for a long period of time, the cells within the muscle tissue will die.
What is the oxygen-carrying protein of the muscle cells?
Myoglobin
How do human muscle cells get oxygen?
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.
When muscle cells are deprived of oxygen they produce?
The muscles will produce lactic acid which feels like the muscles are burning.
What builds up in human muscle cells that are deprived of oxygen?
lactic acid
How long can cardiac muscle be deprived of oxygen before the cardiac muscle cells start to die?
5 minutes
When muscle cells are oxygen deprived the heart still pumps, what must the heart cells be able to do?
It must be able to continue aerobic metabolism when skeletal muscle cannot
What must the heart do when muscle cells are oxygen deprived?
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.
What process allows muscle cells to continue to release energy in the absence of sufficient oxygen?
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.
When no oxygen is present for muscle cells after glycolysis what will the cell produce?
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.
Why the oxygen concentration in muscle cells may be low during vigorous activity?
During vigorous activity, muscle cells require more oxygen to produce energy through aerobic metabolism. However, the rate of oxygen consumption may exceed the rate at which oxygen is delivered to the muscle cells, leading to a low oxygen concentration. This can result in the switch to anaerobic metabolism, producing lactic acid and leading to muscle fatigue.
Why would muscle cells bother with fermentation?
Fermentation is a way to produce energy when there isn't enough oxygen available.
Muscle cells when an individual is excerising heavily and when the muscle becomes oxygen deprived convert pyruvate to lactate What happens to the lactate in the skeletal muscle cells?
The lactate is taken to the liver and converted back to pyruvate.
How do a muscle produce ATP?
creatine phosphate, anerobic cellular respiration, and areobic cellular respiration all produce ATP.
What is site of aerobic respiration?
it happens in all cells in the body when they are deprived of oxygen.
