why our body need to produce lactic acids under insufficient supply of oxygen?

Question

what is/are benefit(s) of producing this lactic acids?
my lecture said it is to avoid the lost of ATP.But how can this lactic acids can help to minimise the lost of ATP?

Answer 1

No matter what, your body needs ATP. In the absence of oxygen, your body will produce ATP using glycolysis. Glycolysis continually uses up NAD however (NAD converted to NADH + H+). In order for glycolysis to continue, the NADH + H+ has to be converted back to NAD. This is what happens when pyruvate is converted to lactic acid. It's a way to recycle the NAD.

Answer 2

The lactic acid is just a waste product of anaerobic respiration. It is harmful to us, but it's better to have a little lactic acid than a bunch of cells die off from hypoxia. So... to produce ATP in the absence of oxygen, cells will use anaerobic respiration and produce lactic acid as its waste. It is a temporary fix.

Answer 3

ATP is a molecule of energy that is produced in our body.so when we do over exercise the body parts sometimes can not get sufficient oxygen and so the glucose is not compleately burnt and hence lactic acid is produced.see something has to be dont to the glucose!but there is no benifit in this rather some difficulty!i think.

Very few must have read this questions and very few answered it though I am also among them a citizen of America before an Indian as we cannot stay a citizen of two countries because being American resident we are no more Indian but we can visit our mother land for ever and are free to live there too loosing all benefits if we stay longer I think , Every body loves peace and hate a place where there is no security . when I see terrorism is a global problem every body should play his or her role . When Malala a muslim girl can fight for education of girls ,when a child wants his or her freedom a terrorist lives in terror and not free from its consequences ,a day would come when people would come forward to wipe it from human minds but it is too late already , there are so many means of destruction to wipe whole humanity if necessary action is not taken sooner . I am too small to take any action ,but all kind of violent films should be removed from media so that we do not have access to them through any means . People can rent these kinds of movies for couple bucks and get up to fight with family members then to next neighbor then at work then somewhere at shopping mall ,then wherever he does not think right triggered by media and resources he can access from cafes and star buck who give this freedom so easily . Then we try to calm the mind which is already bombarded with so much negative information all over the world .

Answer 5

lactic acid is the result of anaerobic metabolism. when we use anaerobic metabolism, ATP yield is just low. However, by using the Cori cycle, we can recycle the lactic acid that was produced into ATP's again.

Answer 6

Lactic acid provides as a catalyst in the glycolytic pathway. To understand more, I can explain but the webpage in my source is better..
