Document Summary

If the ato demand is changed, the speed of the reaction will have to change to match that demand. Glycolysis control: changes in atp production (metabolic pathway must control this) In the krebs cycle, cs (citrate synthase) and isocitrate dehydrogenase will be the regulatory enzymes: all three enzymes determine ultimate speed of the pathway. In 10s or less, it is the atp-pcr system that will give you the energy: later on (i. e. 6/7/10s), you start to get a significant contribution from the glycolytic pathway. I. e. hitting a baseball, jumping, throwing discus predominantly atp. January 11th, 2017: without any/little involvement with pcr. Details of anaerobic metabolic pathways atp-pcr: the concentration of those high energy phosphates in the cell, there is much more. Pcr than atp: the concentration of pcr is 4-5 times that of atp, this system provides energy at a high rate but has a low capacity.
