In contrast to the alactic anaerobic energy system, which uses. stored from previous cellular respiration in combination with a. phosphate buffer, the lactic anaerobic energy system must directly recruit the active cellular respiration process to provide. energy.he alactic anaerobic energy system provides its. energy through a combination of. already stored in the muscles (about 1 or 2 seconds worth from prior cellular respiration during rest) and its subsequent rephosphorylization (about 8 or 9 seconds worth) after use by another molecule called phosphocreatine (.
