When an individual is exercising heavily and when the muscle becomes oxygen-deprived, muscle cells convert pyruvate to lactate.
What happens to the lactate in skeletal muscle cells? a. It is converted to NAD+.
b. It produces CO2 and water.
c. It is taken to the liver and converted back to pyruvate.
d. It reduces FADH2 to FAD+.
e. It is converted to alcohol.
In anaerobic conditions or when the oxygen is limited, the pyruvate enters the anaerobic respiration.
During heavy exercise when the ATP is required in high amount then then oxygen is also required in high amount but due to lack of oxygen, pyruvate formed as a result of the glycolysis is converted to lactate. Lactate acts as electron acceptor taking the role of the oxygen.
This lactic acid diffuses into the blood plasma which is then carried to the liver. In the liver Cori cycle converts the lactate back to the pyruvate form or glucose form.
Your first action in managing this patient should be TO PERFORM A JAW THRUST. The jaw thrust is a first aid strategy that is usually perform on trauma patients in order to prevent the tongue from blocking the upper airways. The jaw thrust should be perform when the patient is in a supine position.
