• Archaea

Question 16

Parts of Prokaryotic Cell

Answer 16

• ribosome
• cytoplasm
• plasma membrane

Question 17

Living Organism

Answer 17

A thermodynamically-open chemical system that self-maintains, self-replicates, and responds to its environment

Question 18

Photoautotroph

Answer 18

Organisms that use light energy to produce organic substances; ex. Plants

Question 19

Eukaryote

Answer 19

Organic substances generate energy by consuming; ex. Humans, animals

Question 20

Entropy

Answer 20

Measure of the disorder of a system

Question 21

Enthalpy

Answer 21

Measure of the loss/gain of heat in a system (H)

Question 22

Gibbs Free Energy

Answer 22

Determines if reaction is spontaneous or non-spontaneous (G)
+G = non-spontaneous, endergonic
-G = spontaneous, exergonic
0 G = @ equilibrium

Question 23

Things that can be determined from G value (3)

Answer 23

1. Direction reaction will proceed spontaneously (spontaneous/non-spontaneous)
2. Amount of useful energy that can be made available by reaction (exothermic/endothermic)
3. Position of equilibrium

Question 24

Things that can not be determined from G value (2)

Answer 24

1. Mechanism of reaction
2. Rate of reaction

(These are determined by kinetics)

Question 25

Covalent Bonds

Answer 25

Atoms share electrons; stronger than non-covalent bonds

Question 26

Non-Covalent Bonds

Answer 26

Atoms do NOT share electrons

Question 27

Electrostatic Interractions

Answer 27

• ionic bonding
• interactions dependent on the electric charges of the atoms
• based off of Coulomb’s Law

Question 28

Coulomb’s Law

Answer 28

E = k q1q2 / ε r

• k = proportionality constant
• q1, q2 = magnitude of charges
• r = distance between charges
• ε = dielectric constants of medium between charges

Question 29

Dispersion Forces

Answer 29

Weak, temporary interactions between molecules

Question 30

Hydrogen Bonding

Answer 30

Strong interaction between a hydrant atom and fluorine, oxygen, or nitrogen; commonly found in proteins and DNA

Question 31

Hydrophobic Interactions

Answer 31

Separation of non-polar molecules from water; commonly found in the cell membrane

Question 32

5 Kingdom Model

Answer 32

• Plants
• Animals
• Fungi
• Protists
• Monera

Question 33

3 Domain Model

Answer 33

• Bacteria
• Eukarya
• Archaea

Question 34

Low vs. High Dielectric Constant

Answer 34

Low Constant = charges are very close together

High Constant = charges are farther apart
