Question 5

Anabolic Pathways

__________________

__________________

Answer 5

Synthesize complex molecules from simpler compounds consuming energy.

Question 6

Energy is_______________

Answer 6

The capacity to do work.

Question 7

The basic types of energy are_____________

&

_____________

Answer 7

Kinetic (Energy of Motion: Movement, Light, Heat)

&

Potentail (Stored energy due to shape or location, or chemical energy stored in the bonds of a molecule)

Question 8

First Law of Thermaldynamics

Answer 8

Energy can be transfered or transformed, but it can not be created or destroyed.

Question 9

The Second Law of Thermaldynamics

Answer 9

Every energy transfer or transformation increases the entrophy of the universe. Whenever energy changes form some “useful” energy is lost. Some energy is randomly dispersed in a form (usually heat) that is not readily available to do work.
