Kevin crоuched аt the stаrting blоck, listening fоr the gunshot thаt would begin the race. When the shot rang out, Kevin lunged forward. The strong contractions of the muscle fibers in his well-conditioned legs got him off to a quick start. The supply of ATP stored in his muscle cells was quickly used up as his muscles worked. Kevin began breathing faster, so that more oxygen would reach his muscle cells, permitting them to do ___ cellular respiration and make more ATPs. The oxygen he was inhaling traveled through his blood and into each of his muscle cells. The oxygen passed into the _ , the organelles called the powerhouses of the cell. The oxygen waited at the bottom of the stage called the _ , and caught the _ which tumbled down the chains. As a result, Kevin's muscle cells were able to obtain 36 - 38 ATPs for each molecule of glucose burned. Kevin used every bit of this energy during the first part of the race. As the race continued, Kevin's muscles required more energy, and therefore more oxygen, so Kevin breathed even more rapidly. Soon, however, he reached a point where he could simply not breathe any faster. His muscle cells began to run out of _ , and he had to switch from aerobic to _ cellular respiration. He was still able to get 2 ATPs from the stage called _ , but that was not enough for his muscle cells, so they started to fatigue. During glycolysis, he was converting glucose to three-carbon molecules called _ , but since he was low on oxygen, he could not send them into the citric acid cycle. Instead, the pyruvates were changed into _ , a toxic substance which accumulated in his muscles and caused them to ___ . (The story continues in Question 2 below).
