<span>The hormone INSULIN is released from the pancreas when blood glucose is elevated above a normal range.
This hormone regulates your blood sugar level. When your blood glucose is elevated above a normal range, the insulin is released from the pancreas. It then attaches itself to the cells and signals them to absorb the excess sugar from the blood stream. 
If your blood sugar level is low, insulin signals the release of stored sugar to the blood stream to maintain the normal level of your blood glucose.</span>

To explain the last sentence, what I mean by that is the sudden decrease in air pollution in just a few weeks is what would have typically taken multiple years to do. Due to less drivers, factories shutting down, and more, less toxic and infirm mental hazardous chemicals were released into the atmosphere in an extremely short amount of time. However, nowdays, it is almost back to where is was before the pandemic.

Answer:
Under anaerobic condition pyruvate is converted into lactate.
Explanation:
Human muscles use both anaerobic and aerobic respiration for the production of ATP. During the starting of intense activity, the oxygen supply is not enough to provide instant energy to the muscle, therefore, muscles use anaerobic respiration to generate ATP.
During anaerobic respiration, muscle do not use oxygen to burn glucose. During anaerobic respiration in muscles, the glucose is converted into pyruvate and then this pyruvate gets convert into lactate and this process is called lactic acid fermentation. In this process, 2 ATP are produced.
