Final answer:
Cellular respiration uses oxygen to generate ATP, and performance may be improved by blood doping, which increases oxygen delivery to tissues, thereby enhancing endurance and performance.
Step-by-step explanation:
Jordan Jones increased his cellular respiration and improved his performance by blood doping. During cellular respiration, a cell uses oxygen to generate ATP. If a person improves his or her performance with blood doping, then we will see increased oxygen delivery to tissues. This means that athletic performance may be enhanced.
One piece of evidence that supports this claim is Card ____. This card states 'In its original intent, the term blood doping was used to describe the practice of injecting by transfusion supplemental RBCs into an individual, typically to enhance performance in a sport.' This suggests that additional RBCs were aimed at increasing oxygen delivery for better performance.
Another piece of evidence that helps this claim is Card ____. This card says 'Endurance athletes may try to boost the availability of oxygen to muscles to increase aerobic respiration by using substances such as erythropoietin (EPO)'. Because of this, there is an intentional increase in RBCs to enhance aerobic capacity.
A very last piece of proof that supports this claim is Card ___. This card says 'With more red blood cells, there is more hemoglobin to help transport the available oxygen.' Which means that the capacity for oxygen transport is elevated, likely improving endurance.
