How do muscles continue to function during exercise as need for oxygen and glucose is increased?
Many of the changes in metabolism during exercise have effects throughout the body. In muscle, there is a increase in blood flow caused by both local factors as well increases in circulating adrenaline. These same hormones also increase the release of glucose into the blood by increasing the break down of glycogen stores. Glucose enters the muscle by because the concentration of glucose outside of the muscle cells is much greater than within (where glucose is being metabolized to make ATP). Oxygen is increased by increases in the rate of respiration and taking deeper breaths. Nonetheless strenuous exercise in muscle results in an energy and oxygen deficit that will lead to the exhaustion of the supply of ATP needed for continued muscle activity.

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.
What can glucose tests detect?
increased blood glucose (hyperglycemia), decreased blood glucose (hypoglycemia), increased glucose in the urine (glycosuria), and decreased glucose in CSF, serous, and synovial fluid glucose.
Another function of the Kreb's cycle other than to continue the breakdown of glucose is to?
Another function of the Kreb's cycle other than to continue the breakdown of glucose is to release energy. It gives the cell more energy to complete other processes.
Why would the respiration of yeast graph not continue to go up in a straight line if the amount of glucose was increased indefinately?
Because glucose is not the only molecule required for respiration, oxygen is also needed, if the amount of glucose was increased indefinatly then the amount of oxygen would decrease rapidly until there is no longer enough. Anaerobic respiration will continue to occur even without oxygen, however, this produces ethanol (in yeast) as a biproduct, when the concentration of ethanol becomes too high, the yeast die.
How does IC change with exercise?
During exercise, the body's insulin sensitivity (IC) typically improves, allowing for more efficient glucose uptake by cells. This enhancement is due to increased blood flow and the translocation of glucose transporters to the cell membrane, facilitating better glucose utilization for energy. Regular exercise can lead to long-term improvements in insulin sensitivity, reducing the risk of insulin resistance and related metabolic disorders. Additionally, intense or prolonged exercise may temporarily lower insulin levels, as the body prioritizes immediate energy needs.
What hormone is increased in the glucose in the bloodstream?
Glucagon
What Animals store glucose in the form of in liver and muscle cells?
Animals store glucose in the form of glycogen in their liver and muscle cells. Glycogen is a polysaccharide that serves as a readily accessible energy reserve, allowing for quick mobilization during periods of increased energy demand, such as exercise. When glucose is needed, glycogen can be broken down into glucose molecules through a process called glycogenolysis.
What are the function of glucagon?
It increase the glucose level.It is produced by function.
What is the function of liver glycogen degradation?
The function of glycogen degradation is to export glucose to other tissues when blood glucose levels are low.
Ways in which glucose is used?
glucose is used for energy so the body can function
What is the function of glycogenolysis?
Glycogenolysis is the metabolic process that breaks down glycogen into glucose molecules, primarily occurring in the liver and muscles. Its main function is to maintain blood glucose levels during fasting or increased energy demands, providing a readily available source of glucose for cellular respiration. This process is crucial for ensuring a steady supply of energy, especially during periods of intense physical activity or between meals.
What is the function of blood glucose?
Glucose provided energy to the cells. It's cell fuel!
