Explain what effects the changes in insulin concentration have on glucose mobilization during exercise?
During exercise, changes in insulin concentration can affect glucose mobilization by stimulating glucose uptake in muscles. When insulin levels decrease during fasting or intense exercise, there is reduced inhibition of glycogen breakdown and increased release of glucose from the liver to maintain blood glucose levels. Conversely, high insulin levels during rest or fed state promote glucose uptake by tissues, decreasing reliance on liver glucose release.
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.
What fuel does the body use for energy during exercise?
mechanical energy
Why do we feel hungry or hungrier after exercise?
During exercise the body depletes its glucose reserves and blood sugar levels fall.
During high intensity exercise, where do muscles primarily get their energy from?
During high intensity exercise, muscles primarily get their energy from stored glycogen in the muscles and glucose in the bloodstream.
What happens during glycolsis in cellular respiration?
glucose is changed into pyruvate
What happens during glucolysis in cellular respiration?
glucose is changed into pyruvate
What happens during the light reaction?
glucose is formed in the form of ATP
When low oxygen levels occur during exercise what end product is glucose converted into?
Energy
What happens to your body when you don't sweat during an exercise?
You will be fat.
What happens to blood flow to kidneys during exercise?
it rises
What is an end product in muscle cells during exercise?
During gentle or moderate exercise, the products of cellular respiration of glucose are carbon dioxide and water (CO2 + H2O), just as in other cells.But if the exercise is vigorous, the muscle cells can switch to anaerobic cellular respiration (fermentation), in which case they convert each molecule of glucose into two of lactic acid.Later, most of the lactic acid is converted back to glucose.
