Question
Chapter 25, Problem 12RQ
a.
Summary Introduction
To determine: The similarities and differences between ATP, ADP, and PCr with respect to exercise.
Introduction: Skeletal muscles have smooth muscles cells present in them. The contraction of these muscles is the first process which takes place during exercise. Exercise is an active process which requires ATP as an energy supplement.
b.
Summary Introduction
To determine: The similarities and differences between myoglobin and hemoglobin with respect to exercise.
Introduction: Mitochondria are the “powerhouse” of the cell. The demand for energy increases during strenuous activity. This energy is produced with the help of oxygen, which enters into the mitochondria through globin proteins.

- Since humans began playing sports there have probably been people willing to cheat to gain an advantage. One form of cheating utilized by endurance athletes is called blood doping, which relates to our study of cellular respiration. “Blood doping is the misuse of certain techniques and/or substances to increase one’s red blood cell mass, which allows the body to transport more oxygen to muscles and therefore increase stamina and performance.” Definition from https://www.wada-ama.org/en/questions-answers/blood-doping From PED, to shaving points, bribery to drugging opponents (https://www.irishtimes.com/sport/maradona-backs-branco-s-claim-of-drug-laced-bottle-at-italia-90-1.4091470), there seems to be countless ways for athletes for gain an advantage.
