Document Summary

Kinetic energy at the atomic, cellular, and molecular levels: small particles diffuse faster than large molecules because they move around farther and faster, movement of particles in a solid crystal are more regular because their location is more regular in space, shape, and interactions, proteins and molecules have motion due to vibrations that allows function from kinetic energy, such as a drug binding to a site on a protein. Potential energy at the atomic cellular and molecular levels: chemical bond energy, atp + h20 (cid:224) adp + pi, metabolism: changes in potential energy associated in changes in chemical bond energy, electrical potential, positive on one side of membrane, negative on other side, negative molecule on negative side wants to go to positive side, concentration gradient, redox potential: willingness of molecules to accept/give up electrons, pressure potential. Intracellular: chromosome movement, vesicale movement, cytokinesis, secretion, plant cell wall, ecm, cellular, flagella, cilia, organisms, muscle contraction.
