What is Metabolism
the totality of an organism’s chemical reaction
what is it called when an organism converts energy into light
Bioluminescence
Energy
the capacity to cause change
what are the forms of energy
Kinetic, thermal, heat, light, potential, and chemical energy
what is kinetic energy
energy associated with motion
what is thermal energy
kinetic energy associated with random movement of atoms or molecules
Heat
is thermal energy in transfer from one object to another
Light
energy that can be harnessed to perform work
what is potential energy
is energy available for release in a chemical reaction
what is the First Law of thermodynamics
energy can be transferred and or transformed, but it cannot be created or destroyed
what is the first law also called
the principle of conservation of energy
what is the second law of thermodynamics
every transfer or transformation increases the entropy of the universe
what is entropy
disorder or randomness
what is equilibrium
Balance
true or false: at equilibrium, forward and reverse reactions occur at the same rate
True
what are the three main kinds of work a cell does
Chemical, transport, Mechanical
what is a catalyst
a chemical agent that speeds up a reaction without consumed by the reaction
what is an enzyme
is catalytic protein
what happens between molecules in every chemical reaction
bond breaking and bond forming
