What are the 3 pathways that muscles get

energy?

DEFINITION 7 Phosphocreatin - by breaking apart, energy is used by muscle-quickest but shortest Anaerobic Glycolysis - glycogen made in skeletal musclefew minutes - produces lactic acidAerobic Respiration (kreb's & electron transport system ETS)forever as lon as their is fuel and oxygen TERM 8

DEFINITION 8

  1. move the skeleton2. maintain posture and body position3. support soft tissue4. guard entrances and exits5. maintain body temperature TERM 9
