What is chemical energy? - Answer✔Potential energy in the bonds between atoms (based on
sharing electrons)
What is electromagnetic radiation? - Answer✔Kinetic energy in the form of radio waves;
microwaves; infrared, invisible, and ultraviolet light; and gamma waves.
What is electrical energy? - Answer✔Kinetic energy associated with the movement of charged
particles
What is mechanical energy? - Answer✔Kinetic and potential energy of objects
What is the first law of thermodynamics? - Answer✔Energy can be neither created nor
destroyed. It can only change form.
What is the second law of thermodynamics? - Answer✔Isolated (closed) systems tend to go
towards disorder (amounts of usable energy decrease during energy conversions)
What is a spontaneous process? - Answer✔1. A process that can occur without the input of
energy
2. For a process to occur spontaneously it must increase entropy within the system
What is an exergonic reaction? - Answer✔Reactions with a negative ^G (products have less free
energy than the reactants)
What is an endergonic reaction? - Answer✔Reactions have a positive ^G (the products have
more free energy than reactants)
What do enzymes do? - Answer✔Encourage reactions by lowing the activation energy
What is oxidation? - Answer✔Removal of electrons from a substance
The removal of what atom is often associated with oxidation? - Answer✔Hydrogen
Do oxidized substances release or absorb energy in a reaction? - Answer✔Release
What is reduction? - Answer✔Addition of electrons to a substance
The addition of what atom is often associated with reduction? - Answer✔Hydrogen
Does reduction absorb or release energy? - Answer✔Absorb
Are oxidation and reduction always together? - Answer✔Yes (Redox reactions)
What is an autotroph? - Answer✔An organism capable of synthesizing complex molecules from
CO2 and other simple inorganic molecules using energy from a non biological source
What are examples of autotrophs? - Answer✔Plants and algae
