Document Summary

Primary function: generate force + produce movement. 3 types of muscle cells: cardiac muscle. Automatic; not under voluntary control allows us to function. 50% of body allows us to accomplish work. Atp allows us to contract muscles for work. Stores energy for a few seconds (allows work for few seconds: when energy is needed, atp convert to adp, to maintain work, atp must be continuously synthesized + replenished. 3 sources of atp: creatine phosphate (cp, aerobic metabolism. Metabolism in presence of oxygen: anaerobic metabolism. Transfers energy to adp to recharge it to atp: acts as a backup energy storage for atp, energy storage is about 4x atp. Atp & cp systems are still very limited. Supply energy for 10 seconds of heavy work. Supply energy for 60 seconds of moderate work. When muscle activities over a long duration, energy must come fm other sources. Supplies most atp when o2 is available: nutrients are burned in presence of o2.
