What is the difference between kinetic and potential energy? Potential energy is stored energy while kinetic energy is the energy of motion
How is energy transferred from one molecule to another? Each time an electron moves between molecules energy goes with it
What is the difference between oxidation and reduction? Reduction is gaining an electron, while Oxidation is the loss of an electron (oxygen is the electron acceptor)
What is free energy? The energy available to do work
What is endergonic and exergonic? Endergonic is a reaction that requires an input of energy while, exergonis is a reaction that releases energy
What is an enzyme? molecules that catalyze reactions in living cells
Enzymes are mostly proteins True
Enzymes lower the activation energy required for a reaction? true
enzymes are not changed or consumed by the reaction true
enzymes interact with substrates true
what is a substrate? molecule that will undergo a reaction
what is an active site? region of enzyme that binds to the substrate
binding of an enzyme to a substate causes the enzyme to change shape which produces a better induced fit between the molecules true
What is ATP Adenosine triphosphate it is the energy of the cells
