Why do Muscle cells need to be supplied with more food when there is a lack of oxygen than when there is plenty of oxygen?
Lactic acid fermentation, which occurs in muscle cells when there is a lack of oxygen, only produces two molecules of ATP per glucose molecule. Aerobic respiration produces 34-38 molecules of ATP per glucose molecule. So, in order to produce enough ATP to function, there needs to be more glucose available.
What else can I help you with?
How is oxygen supplied to the skeletal muscle?
Oxygen is transported by red blood cells and is released into tissues as they pass through capillaries in the tissue.
How is energy supplied to muscle fibers for contraction?
Energy to muscles is supplied through mitochondria making ATP using oxygen. Muscle cells use a tremendous amount of energy so they have large numbers of mitochondria.
When muscle cells or do work they need more food and oxygen?
When muscle cells perform work, they require more energy, which is supplied by food in the form of glucose and oxygen from the blood. During physical activity, the demand for oxygen and nutrients increases to support the muscle's energy needs for contraction and movement. This process is essential to sustain muscle function and prevent fatigue during exercise.
How does a blocked artery cause less oxygen to reach the heart?
Arteries carry blood, oxygenated by the lungs, to the cells of the body. Since the heart is a large muscle, its cells need oxygen too. When one of the arteries supplying the heart with oxygenated blood is blocked ("occluded") the oxygen cannot reach the cells supplied by that artery.
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.
During exercise muscle cells use what?
During exercise muscle cells use oxygen.
What gas do muscle cells need?
All cells need Oxygen.
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.
Is the iron-containing protein in muscle cells that controls oxygen uptake from red blood cells?
The iron-containing protein in muscle cells that controls oxygen uptake from red blood cells is called myoglobin. Myoglobin helps muscles store and release oxygen as needed during muscle contraction.
What is the oxygen-carrying protein of the muscle cells?
Myoglobin
Are there oxygen cells in the muscle system?
I dont think there are such things as oxygen cells. However, there are red blood cells (erythrocytes) that have hemoglobin, a molecule that oxygen can bind to. Throughout literally every cell in your body, there are capillaries. These capillaries deliver red blood cells to all of your cells, including your muscle cells.
How does the body transport oxygen to cells?
Oxygen is supplied to the body tissues by a series of blood vessels from arteries, arteriolles, to capillaries.
