The mass extinctions that occurred 250 million years ago and 65 million years ago may have been due to gradual process or Catastrophic events.
Answer No 1:
Process 1 is cellular respiration. Cellular respiration can be described as a process in which glucose and oxygen are converted into water and carbon dioxide. ATP is released by this process which is used as an energy source.
Process 2 is anaerobic respiration. It is a process which occurs in the absence of oxygen. This process will also yield ATP.
Answer No 2:
The process 1, cellular respiration, is known to produce 38 molecules of ATP. Out of these, 2 molecules are the result from the process of glycolysis, 2 molecules arise from Kreb's cycle, rest 34 are known to occur from the electron transport chain.
The process of anaerobic respiration is known to make 2 molecules of ATP in total.
