Document Summary
There are three main types of biological energy systems: phosphagen system, glycolysis, and. All three systems produce atp at different capacities (how much is created and how fast it is created). Each system results in the intensity and rate of the activity and the duration of the activity. Energy is needed in the body to do work, although energy must be converted to atp for it to be useful. Ex: the body is like a slot machine that runs on quarters. If you have a dollar you will need to make it into quarters before you can use the machine. This is an intermediate amount of energy which is good since it does not release too much energy in its breakdown (exergonic) and doesn"t take up too much energy to regenerate (endergonic). During muscle contractions, an enzyme called myosin atpase, hydrolyzes atp (adds a hydrogen to atp) which creates mechanical energy that is released in 25% movement and 75% heat.
