The substance that accumulates in the muscle during anaerobic glycolysis is known as:
|
|
phosphate creatine
|
|
|
triglyceride
|
|
|
lactic acid
|
|
|
ATP
|
Explanation:
Detailed explanation-1: -Lactate formed during anaerobic glycolysis enters the gluconeogenic pathway after oxidation to pyruvate by lactate dehydrogenase. After intense exercise, the lactate produced diffuses from the muscle into the blood and is taken up by the liver to be converted into glucose and glycogen.
Detailed explanation-2: -During high intensity exercise the products of anaerobic glycolysis namely pyruvate and H+ accumulate rapidly. Lactate is formed when one molecule of pyruvate attaches to two H+ ions.
Detailed explanation-3: -In aerobic glycolysis, pyruvate is converted to lactic acid by lactic acid dehydrogenase-A (LDHA).
