Compare and contrast between the two ATP generating energy systems: phosphagen system and the anaerobic glycolytic system. Base your answer on five different properties of each system and/or the type of activities they support.

Please write the answer for not a biology major (not too complex plz)

Answer 1

1) Phosphagen system uses creatine phosphate (CP) and has a very rapid rate of ATP production. On the other hand, anaerobic glycolytic system does not require oxygen and uses the energy contained in glucose for the formation of ATP.

2) In phosphagen system, the creatine phosphate is used to reconstitute ATP after it’s broken down to release its energy. On the other hand, anaerobic glycolytic pathway occurs within the cytoplasm and breaks down glucose into pyruvate.

3) In phosphagen system, the total amount of CP and ATP stored in muscles is small, so there is limited energy available for muscular contraction. On the other hand, anaerobic glycolytic pathway is an intermediate pathway between the phosphagen and aerobic system, anaerobic glycolysis can produce ATP quite rapidly.

4) In phosphagen system, energy is instantaneously available and it is essential at the onset of activity as during short-term high-intensity activities. On the other hand, anaerobic glycolytic pathway can use the energy during activities requiring large bursts of energy.

5) The phosphagen system lasts about 1 to 30 seconds in duration, such as sprinting. Anaerobic glycolytic pathway lasts somewhat longer periods of time (30 seconds to three minutes max, or during endurance activities prior to steady state being achieved).
