Resynthesis of creatine phosphate in human muscle after exercise in relation to intramuscular ph and availability of oxygen , atp, adp, cp, creatine, lactate and . Energy systems and the human body and exercise lactic acid system, atp-pc system, anaerobic respiration, krebs cycle and more. Key points of atp-pc system provides energy for atp re-synthesis for 3-10 seconds how the energy released aids atp resynthesis some will be able to relate atp .

Here is the resynthesis equation: energy + adp +p = atp allow muscle cell sarcoplasm to contain more atp and creatine so atp-pc system provides energy for longer . Energy system responses to acute exercise atp pc lactic acid aerobic atp pc lactic acid aerobic atp resynthesis phosphocreatine anatomy and physiology atp resynthesis home wilmot hm .
The atp/pc system will be predominant for the first 10 seconds, until the fuel source (creatine phosphate) is depleted causing a shift to the lactic acid system the lactic acid system will continue to resynthesis atp however will also cause lactic. The atp-pc system neither uses oxygen nor produces lactic acid and is thus said to be alactic anaerobic here is the resynthesis equation: energy + adp +p = atp . Chapter 5: energy systems the concept that more than one energy system contributes to atp resynthesis intensity of activity for atp-pc system. The anaerobic (atp-cp) energy system adenosine triphosphate (atp) stores in the muscle last for approximately 2 seconds and the resynthesis of atp from creatine phosphate (cp) will continue until cp stores are depleted, approximately 4 to 6 seconds.
Factors affecting the rate of phosphocreatine resynthesis following intense exercise the second anaerobic energy system relies upon a series of nine different . The hydrolysis and resynthesis of atp is thus a circular process—atp is the aerobic system produces 18 times more atp than does anaerobic glycolysis there are two systems within anaerobic metabolism, which are the atp-pc system and the lactic cellular respiration is the process that takes place in cells. The atp-pc energy system is the system by which the body fuels 10 to 20 seconds of intense exercise by using stored atp, the high-energy molecule that fuels muscles, and then through phosphocreatine, which is quickly converted to atp to further fuel muscle contractions this system is also sometimes . The atp-pc system is the body's first energy system to respond to depleting atp stores phospocreatine and it's role in resynthesis of atp phospocreatine (pc) is . Energy systems fatigue & recovery phosphate to adp to resynthesis atp the breakdown of pc does not require the presence of oxygen, therefore the atp-pc system .
Atp resynthesis is the process by which the body and its muscles produce atp atp is the main energy source of almost all living things, and while atp is not energy itself, it temporarily stores energy in its bonds to be released on demand humans resynthesize atp through three metabolic pathways . The power of an energy system refers to the maximal rate at which the system can produce atp, while the capacity of an energy system refers to the potential that system has for atp resynthesis atp-pcr. The atp/pc system provides energy via coupled reactions, to resynthesis adp back into atp when atp levels fall and adp levels increase this stimulates the release of the enzyme creatine kinase, which breaks down the pc bond releasing energy this energy is not used in muscular work but is coupled .
Energy systems used when running the harder you run the more atp is required and the more resynthesis has to occur the anaerobic energy system creates . Human body's response to exercise as discussed on the energy systems page the atp-pc system can only last muscles begin to fatigue when atp resynthesis can no . The idea of pc breakdown to permit atp resynthesis should be added to the diagram, but make sure it goes on the left-hand/anaerobic side, as no oxygen is involved as a final analogy to explain how the systems work together during an activity, students might like to consider driving a car.
