When low oxygen levels occur during exercise and glucose is converted into what stable end products?
pyruvic acid
How can Plasma glucose levels during exercise increase?
The blood glucose is used by the muscles during exercise. The level of the glucose in the blood drops down. This stimulates the secretion of the hormone called as glucagon. This glucagon is secreted by the alpha cells of the endocrine part of the pancreas.
Why does your face go red during exercise even though the sympathetic nervous system is activated which should divert your blood away from the skin and to your muscles instead?
The control of blood flow during exercise is more complicated than at first glance. At lower intensity exercise or at the start of exercise one of the main problems is heat. The blood carreis heat from the core to the skin allowing it to escape. During exercise heat would build up to dangerous levels is this system wasnt in place. However after more time the requirement of the muscles for oxygen outweighs the need to remove heat and so the blood flow to the skin is cut preserving more to flow to the the muscles.

What happens to the levels of carbon dioxide and water during aerobic exercise compared to their levels when the performer is at rest?

What effect does rapid exhalation of CO2 during excerise have on the concentration of H2CO3 in the blood?
During exercise it has no effect. Without the exercise it would lower the CO2 (or H2CO3) levels.
When low oxygen levels occur during exercise what end product is glucose converted into?

What is the effect of edta on mcv hct esr?

What are the disadvantages of anaerobic exercise?
