  • Metabolic Pathway

    Series of chemical reactions that either builds a complex molecule(anabolic pathway) or breaks down a complex molecule ( catobolic pathway)

  • Catabolic pathway

    A metabolic pathway that releases energy by breaking down complex molecules to simple molecules

  • anobolic molecule

    a metabolic pathway that consumes energy to synthesize a complex molecule from simple mollecule

  • Biogenetics

    Overall flow and transformation of energy in organsims. (study of how energy flows through organisms)

  • Kinetic Energy

    Motion of object

  • Thermal Energy

    Kinetic energy associated with random movment of atoms or molecules

  • Heat

    Thermal Energy transferring from one to another called heat

  • Potential Energy

    Objects not presently moving; may still pass energy; energy not called kinetic

  • chemical energy

    Energy available in molecules for release in a chemical reaction ( form of potential energy)

  • Thermodynamics

    Study of how energy moves and changes from one form to another

  • First Law of thermodynamics

    Energy can be transfered and transformed but it cannot be created or destroyed.

  • Second Law Of thermodynamics

    Every energy tranformation/transfer increases the entropy of the universe. (converted into heat) ( Makes universe messy and disordered)

  • Entropy

    measure of moleculer disorder or randomness

  • spontanous process

    Process that occur within an overall input of enery process that is energeticall favorable (happens own its own)

  • Nonspontanous process

    needs a push like water flowing back on hill needs a pump to do so

  • FREE ENERGY

    Useful energy available to do work

  • gravitational Motion

    Objects move spontansouly from higher altitude to lower altitude

  • Exergoinc Reaction

    A chemical reaction where there is a net release of free energy.

  • endergonic Reaction

    Chemical energy where free energy is absorbed

  • Do Exergonic reactions have negative gibb energy

    Exergonic reactions release energy and have a negative ΔG because free energy decrease

  • Do Endergonic reactions have negative gibb energy

    Endergonic reactions require energy and have a positive ΔG because free energy increases. The greater the energy released by an exergonic reaction, the more work it can potentially do.

  • Is higher-free-energy state more stable relative to other

    A lower-free-energy state is more stable relative to the higher-free-energy state.

  • What is a spontaneous change?

    It means something happens naturally without needing a constant supply of energy to make it happen.

  • During a spontaneous change, what happens to free energy

    During a spontaneous change, the system's free energy decreases.
