A Biking Trip

Last week i went bike riding with Zev. While bike riding I realized that biology is everywere. We passed by trees that where making energy through a proccess called photosynthesis. Because Zev does not have and leaves or chloraphyll, he breaks down food into Glucose which is then broken down for energy or stored. Like the trees, Zev is using and making energy. Energy is the capacity to perform work, in this case, pedal his bike. The are two kinds of energy: kinetic and potential. When Zev is on his bike sitting at the top of a hill, that is an example of potential energy. ATP or, Adenine triphosphate, is the cells choice of energy source. In the mitochondria a process called respiration breaks down compounds such as glucose from foods to obtain ATP. When the ATP is used by the body, phosphorylation recharges the ADP, or Adenine Diphosphate, to return it to its original state. Using ATP Zev taking me on a fun and exiting 15 mile bike ride along the Randolph trails. Because i am the Traveling PBWiki Shirt, I reminisce about the past adventures I have had.
