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

capability capability - the ability to do work (move matter) 2 types: Kinetic Energy - efficiency doing work ex: awaken (moving molecules) light Potential Energy­­ - stored get-up-and-go; can be as a result of location or appointment array ex: roller coaster - at one C ft high in that location is more authorisation cleverness than at 25 ft high cells - molecules turn out potential energy due to the arrangement of the atoms Chemical Energy - potential energy of molecules important for living organisms Thermodynamics Thermodynamics - cogitation of energy trans digitations in matter 1st Law of Thermodynamics: Energy cannot be created or destroyed simply transferred or transformed ex: electric company doesnt create energy, it transmutes it to a in operation(p) form; car converts gasoline (potential energy) into kinetic energy; we convert intellectual nourishment into kinetic energy 2nd Law of Thermodynamics: Energy conversions dishonor crop in the universe (when en ergy is converted into other form, there is an increase in indisposition or randomness) mho - the amount of disorder in a system shake up is a form of disorder (random molecular(a) motion) ex 1: discharge in tank of car - only of the chemical energy that is converted into kinetic energy will lastly be converted into heat energy. When stopping car, the friction between the tires and the lane and the brakes and the tires creates heat.

ex 2: Cells - creates staged structures from less organised ones (ex: formation of proteins) but surroundings become less organized because some energy escapes as heat **Work of cells is cater by the potential energy contained in molecules Pro! blem: expound 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...
