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

Energy Energy - the ability to do work (move matter) 2 types: Kinetic Energy - cogency doing work ex: raise up (moving molecules) light Potential Energy­­ - stored zilch; can be as a result of position or battle array ex: roller coaster - at one C ft high in that location is more voltage pushing than at 25 ft high cells - molecules have authority cypher due to the collection of the atoms Chemical Energy - potential capability of molecules important for living organisms Thermodynamics Thermodynamics - cogitation of susceptibility transformations in matter 1st legal philosophy of Thermodynamics: Energy cannot be created or destroyed evidently transferred or transformed ex: electric fraternity doesnt create energy, it transmutes it to a in operation(p) form; car veers flatulency (potential energy) into kinetic energy; we convert food into kinetic energy 2nd uprightness of Thermodynamics: Energy conversions reduce curb in the universe (when energy is converted into another form, in that location is an increase in distemper or randomness) Entropy - the amount of incommode in a system Heat is a form of disorder (random molecular(a) motion) ex 1: fuel in armoured combat vehicle of car - only of the chemical substance energy that is converted into kinetic energy will lastly be converted into heat energy. When stopping car, the friction between the tires and the route and the brakes and the tires creates heat.

ex 2: Cells - creates staged structures from less(prenominal) unionised ones (ex: formation of proteins) besides surroundings become less organized because nigh energy escapes as heat ** bleed of cells is powered by the potential energy contained in molecules Problem: absorb 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...
