• Enzymes

Energy is..

• The capacity to perform work• Kinetic Energy: actually doing work• Heat: energy associated with

movement of molecules• Potential Energy: capacity to perform

work

Thermodynamics

• Study of energy transformation• 1st law: conservation of matter• 2nd law: energy conversions reduce

the order of the universe (aka: increase disorder [entropy]).

Chemical Reactions

• Endergonic: requires a net input of energy.

Chemical Reactions

• Exergonic: a reaction that releases energy.

Enzymes

• Lower the activation energy of a reaction
