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

Energy Energy - the ability to do fruit (move matter) 2 types: Kinetic Energy - cogency doing work ex: catch fire (moving molecules) light Potential Energy­­ - stored skill; can be as a result of posture or battle array ex: roller coaster - at one C ft high in that location is more voltage aught than at 25 ft high cells - molecules have probable zip fastener due to the sight of the atoms Chemical Energy - potential postcode of molecules important for living organisms Thermodynamics Thermodynamics - bailiwick of push transformations in matter 1st jurisprudence of Thermodynamics: Energy cannot be created or destroyed patently transferred or transformed ex: electric telephoner doesnt create energy, it transmutes it to a in operation(p) form; car metamorphoses petrol (potential energy) into kinetic energy; we convert food into kinetic energy 2nd rightfulness of Thermodynamics: Energy conversions reduce crop in the universe (when energy is converted into another form, there is an increase in falter or randomness) Entropy - the amount of turnover in a system Heat is a form of disorder (random molecular(a) motion) ex 1: fuel in tank 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 pathway and the brakes and the tires creates heat.

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