Why does lactic acid production increase during intense exercise EVEN THOUGH THERE IS PLENTY OF OXYGEN AVAILABLE?
Homework Answers
Answer:
During more intense excercise the pyruvate formed in the glycolysis will be reduced to lactate because it is formed at a rate exceeding the capacity of maitochondria to oxidize it even if there is plenty of oxygen available.

During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction. Lactic acid has a p?a of 3.86. Lactic acid dissociates into the lactate ion and a hydrogen ion. The...

1 a) A sudden increase in lactic acid levels during exercise can lead to metabolic acidosis. Acidosis is commonly treated by administering NaHCO, intravenously. Using the bicarbonate-carbon dioxide buffer system, qualitatively explain the effect of this procedure on blood pH. [6 points) b) The phosphate buffer system is another buffer system in the blood. Phosphates are found in the blood in two forms: sodium dihydrogen phosphate (Na2H2PO4), which is a weak acid, and sodium monohydrogen phosphate (Na2HPO 2), which is...

It is known that the liver removes much of the lactic acid during exercise. At increasing intensities of work, the liver is unable to remove lactic acid as well due to reduced blood flow, and this is thought to be tied to the sympathetic nervous system activation. Explain how sympathetic NS activation will reduce liver function while increasing muscle blood flow.

In blood, pH is buffered to a constant value of 7.4 During exercise, your muscles generate lactic acid, HC3H50, (K = 1.4x10-4). Will the lactic acid be mostly protonated, mostly deprotonated, or in roughly equal concentrations? a) It will be mostly protonated (lactic acid) b) It will be mostly deprotonated (lactate) c) It will exist in roughly equal concentrations of lactic acid and lactate d) The lactic acid/lactate ratio cannot be determined from this information OLISCHIC SCI SCHC COLCHONCO HSU...
