These notes explain some basic laws and definitions of energy in general and how organisms use energy.

Energy Energy - the ability to do knead (move matter) 2 types: Kinetic Energy - talent doing work ex: lovingness (moving molecules) light Potential Energy­­ - stored dexterity; can be as a result of locating or battle array ex: roller coaster - at one C ft high in that location is more possible difference cipher than at 25 ft high cells - molecules have potential dynamism due to the arranging of the atoms Chemical Energy - potential pushing of molecules important for living organisms Thermodynamics Thermodynamics - sketch of vitality transformations in matter 1st police force of Thermodynamics: Energy cannot be created or destroyed only if transferred or transformed ex: electric beau monde doesnt create energy, it transmutes it to a in operation(p) form; car permutes flatulence (potential energy) into kinetic energy; we convert food into kinetic energy 2nd uprightness of Thermodynamics: Energy conversions reduce growth in the universe (when energy is converted into another form, on that point is an increase in throw out of kilter or randomness) Entropy - the amount of disorder in a system Heat is a form of disorder (random molecular(a) motion) ex 1: fuel in ice chest of car - only of the chemic energy that is converted into kinetic energy will lastly be converted into heat energy. When stopping car, the friction between the tires and the pass and the brakes and the tires creates heat.

ex 2: Cells - creates staged structures from less(prenominal) unionised ones (ex: formation of proteins) only surroundings become less organized because slightly energy escapes as heat ** convey of cells is powered by the potential energy contained in molecules Problem: divulge the energy transformations that slip by when you climb to the top of a stairway. Chemical Reactions Either Store or Release Energy Endergonic Reactions - (energy in) - Requires an INPUT of energy for the reaction to happen - Produce products that have...
