Document Summary
Evaluate the change in free energy in a given reaction to determine if it is exergonic or endergonic. Atp as an example of chemical potential energy. What we will focus on for atp. In the bounds of the large repulsive phosphate groups. Take macromolecules and break them down into smaller subunits. Energy can go to the synthesis of atp. The amount of usable energy: gibbs free. Reactants contain more energy than the products. Positive delta h = more chemical energy in bonds. Negative delta h = less chemical energy in bonds. Metabolism: refers to all the chemical reactions that are occurring in your body at the same time. Atp is less stable , they are repelling one another. Adp + phosphate -> atp + h2o (dehydration synthesis) Rearrange itself when you add a 3rd phosphate group on. Coupling can allow for exergonic reactions to occur. All cell communications are based on changes in shape.
