PLEASE HELP, THIS IS DUE SOON! In biochemical terms, explain what causes lactic acid buildup. (Your answer must include the words: anaerobic, oxygen, lactic acid, ATP)

Lactic acid builds up in the muscles of mammals due to inadequate oxygen.

During rigorous activities, oxygen supplies become inadequate to generate the necessary energy in the form of ATP from normal aerobic respiration.

Thus, anaerobic respiration is used to supplement the energy needed during rigorous activities.

During aerobic respiration, the presence of oxygen ensures that the 3 steps are complete:

For anaerobic, only glycolysis takes place and the pyruvate molecules generated are converted to lactic acid. In the presence of adequate oxygen, the lactic acid is converted back to pyruvates which then move into Kreb's cycle.

The 2 molecules of ATP generated from glycolysis are used to supplement the energy needed during rigorous activities.

Lactic acid buildup occurs when there's not enough oxygen in the muscles to break down glucose and glycogen. This is called anaerobic metabolism. There are two types of lactic acid: L-lactate and D-lactate. Most forms of lactic acidosis are caused by too much L-lactate.

Explanation:

hope it helps

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
