Chap. 8 (and maybe 9)

Question 1

What is Fermentation?

Answer 1

A partial degradation of sugars that occurs without Oxygen (O,2)

Question 2

What is Thermal Energy?

Answer 2

Kinetic energy associated with random movements of molecules and atoms

Question 3

What is Kinetic energy?

Answer 3

Energy associated with the relative motion of objects

Question 4

What is Chemical Energy?

Answer 4

Potential energy available for release in a chemical reaction

Question 5

What is Potential Energy?

Answer 5

Energy that isn’t in motion

Question 6

2nd law of Thermodynamics

Answer 6

Every energy transfer or transformation increases the entropy in the universe

Question 7

1st Law of Thermodynamics (aka Principle of Conservation of Energy)

Answer 7

Energy can be transferred or transformed, but can’t be created or destroyed

Question 8

Catabolic Process

Answer 8

Aka Breakdown pathway - A process that releases energy as it breaks down complicated molecules to form simpler ones

Question 9

Anabolic Process

Answer 9

A process that consumes energy as it builds complicated molecules from simple ones

Question 10

Spontaneous process

Answer 10

Increase of entropy without energy (doesn’t require outside input of energy)

Question 11

Non-Spontaneous Process

Answer 11

Decrease of entropy with energy supplied (happens on its own)

Question 12

(Triangle) G

Answer 12

Change in free energy

Question 13

(Triangle) H

Answer 13

Change in total energy

Question 14

T

Answer 14

Absolute temperature

Question 15

(Triangle) S

Answer 15

Change in entropy

Question 16

Endergonic Reaction

Answer 16

A non spontaneous reaction that stores and gains free energy from it’s surroundings (G is positive)

[German-Gains Energy]

Question 17

Exergonic reaction

Answer 17

A spontaneous reaction that releases (free) energy during the breakdown of organic molecules (G is negative)

[Rockstar-Releases]

Question 18

Free Energy

Answer 18

Energy that works when temperature and pressure are the same
