Campbell's Biology Chapter 8

Front 1

metabolism

Back 1

totality of an organism's chemical reactions.

Front 2

metabolic pathway

Back 2

begins with a specific molecule, which is then altered in a series of defined stemps, resutliting in a certain product.

Front 3

catabolic pathways

Back 3

break down pathways

Front 4

anabolic pathways

Back 4

consume energy to build complicated molecules from simpler ones; sometimes called biosynthetic pathways.

Front 5

bioenergetics

Back 5

study of how organisms manage their energy resources

Front 6

energy

Back 6

the capacity to cause change

Front 7

kinetic energy

Back 7

energy associated with the relative motion of objects

Front 8

heat (thermal energy)

Back 8

kinetic energy associated with the ramdom movmeent of atoms or molecules.

Front 9

potential energy

Back 9

an object not presently movimg may still possess energy. energy that is not kinetic energy.

Front 10

chemical energy

Back 10

a term used to refer to the potential energy available for release in a chemical reaction.

Front 11

thermodynamics

Back 11

study of energy transfomations that occur in a collection of matter.

Front 12

first law of thermodynamics
(principle of conservation of energy)

Back 12

energy can be transferred or transformed, but it cannot be created or destroyed.

Front 13

entropy

Back 13

a measure of disorder or ramdomness.

Front 14

second law of thermodynamics

Back 14

Every energy transfer or transformation increases the entropy of the universe.
