Document Summary

1 cycle of a row takes about 1-1. 5 seconds (very slow compared to sprinting: contraction speed 1/10th of a second) Same gram of fat gives you over twice the amount of energy. Makes much more sense for the body to store the energy as fat. More hydrogens in fat: hydrogens are key to supply electron transport chain to give us atp. Number of hydrogens is important because that gives indication of energy production that"s possible. When we store glucose as glycogen, glucose molecules are held together by water. More water increases the weight of the cell, but not the energy. You don"t change the energy you get from each mole of glucose. You add water so you can bind molecules together, but this doesn"t increase the energy stored. Makes more sense to store energy as fat because you don"t have to store it with the extra water involved. Cho weighs more when stored due to water bond.
