Oxygen debt is the deficit of oxygen resuting from intense exercise. During exercise, the body cannot generate enough ATP (energy) to meet the needs of the muscle. This produces lactic acid, which causes muscles to fatigue. Oxygen is required to metabolize the lactic acid and replenish energy stores. How do we do this? We breath, rapidly to bring in large amounts of oxygen. Think of this concept as a checkbook with money being oxygen and writing checks as exercise. If you write checks, but run out of money, your account will go into debt. How do you get out of debt? You get more money.

What else can I help you with?
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.
What is the role of the Myoglobin?
Myoglobin is a protein found in muscle tissue of vertebrates that is iron- and oxygen-binding. It is a primary oxygen-carrying pigment of muscle tissues and is related to hemoglobin, but only found in the bloodstream after a muscle injury.
What triangular shaped muscle area within the bladder contracts during urination?
The detrusor muscle is the main muscle within the bladder that contracts during urination to help expel urine. It is a smooth muscle that forms a triangular shape at the base of the bladder.
What molecule present primarily within oxidative skeletal muscle cells as an oxygen buffer due to its ability to bind oxygen?
Myoglobin
How does the presence of lactic acid contribute to the development of muscle fatigue during physical activity?
During physical activity, muscles produce lactic acid as a byproduct of energy production when oxygen levels are low. The accumulation of lactic acid can lead to a decrease in pH levels within the muscle cells, causing fatigue and a decrease in muscle performance.
The vessels that carry oxygen to mycardial cells are called what?
Coronary arteries carry oxygen-rich blood to the tissues of the heart muscle. The oxygen diffuses within myocardial capillaries.
Do t tubules play a role in storing calcium within muscle cells?
Yes, T-tubules play a role in storing calcium within muscle cells by helping to facilitate the release of calcium from the sarcoplasmic reticulum during muscle contraction.
What does intramuscular use mean?
Into The Muscle; Within The Muscle
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.
The connective tissue covering muscle cells?
The connective tissue covering muscle cells is called endomysium. It surrounds individual muscle fibers within a muscle and provides support and structure to the muscle tissue. Additionally, it contains capillaries that supply nutrients and oxygen to the muscle cells.
How does seasonal turnover in lakes affect oxygen level available to the aquatic organisms?
It affects the oxygen level because it is essential for the survival and growth of organisms ata ll levels within its ecosystem.
Which muscle has tissue of the circulatory pump?
The heart is the muscle that functions as the circulatory pump within the body. It is responsible for pumping blood throughout the circulatory system to deliver oxygen and nutrients to the body's tissues and organs.
