what is energy used for

growth, repair, reproduction, protection, healing, tempreature maintenance, mobility

what are the different types of energy

kinetic, free, potential, chemical potential

what is free energy

the energy that is available to do work

what is kinetic energy 

energy that is belonging to motion 

what is chemical potential energy

stored energy that creates bonds or is released when bonds are broken

what is potential energy

energy that is stored o an abject as a result of its position relative to something else

how many laws of thermodynamics 

2 

what are the two laws of thermodynamics

energy is not created or destroyed. t is only converted from one form to another. also during eerngy conversion, some energy became unstable and increases the entropy of the universe 

what is the entropy 

it is the scientific concept that measrure disorder or randomness in a system or the dispersal of energy in an object

what are the different types of reactions in terms of energy

anabolic or catabolic

what si anabolic

a reaction that needs energy to go from small to big

what I catabolic

a reaction that releases energy as it goes from big to small

what is metabolism

anabolism + catabolism

what is a redoc reaction

a reaction in whcih there is reduction or oxidization - and electrons are lost or gained 

what are the different types of reactions in terms of heat

exergonic or endergonic

exergonic is what

releases energy (heat) as the reaction goes on over time

endergonic is what

uses or requires energy (heat) as the reaction goes on over time

what are the different types of reactions in terms of oxygen

aerobic or anaerobic

what is aerobic 

reactions that need oxygen to carry out their function 

what is naeorboic

reactions that dont use oxygen to produce energy
