What else can I help you with?
How long can cardiac muscle be deprived of oxygen before the cardiac muscle cells start to die?
5 minutes
What do muscle cells produce when they are deprived of oxygen?
The muscles will produce lactic acid which feels like the muscles are burning.
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
When muscle cells are deprived of oxygen they produce?
The muscles will produce lactic acid which feels like the muscles are burning.
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.
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.
What is site of aerobic respiration?
it happens in all cells in the body when they are deprived of oxygen.
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.
When fermentation occurs in muscle cells muscle fatigue is called by the production of?
Lactic acid builds up and causes muscle burn.
During exercise muscle cells use what?
During exercise muscle cells use oxygen.
What gas do muscle cells need?
All cells need Oxygen.
