24
What else can entropy be called
Chaos, randomness
25
Define metabolism
Sum or all of catabolic and anabolic reactions within a cell or organism
26
Define catabolism
Energy stored in organic molecules released (makes energy)
27
What happens in a catabolic reaction
Pathways are degradative
28
Define anabolism
Energy is consumed to build a complicated molecules from simpler ones
29
What happens in anabolic reaction
Pathways are biosynthetic
30
Describe a degradative reaction
Breaking down- hydrolysis
31
Describe A biosynthetic reaction
Building up- dehydration synthesis
32
What happened during a hydrolysis action
Water is used to split one large Molecule into two smaller molecules (polymers into monomers)
33
What happens during a dehydration reaction
Water is released into small molecules are joined together to generate one large molecule (monomers and polymers)
34
What is delta G
The energy difference between the products and reactants
35
How is delta G calculated
Total product energy minus total reactant energy
36
Define exergonic in terms of delta G
High energy reactants are converted into low energy products
37
If a reaction is exergonic what is the energy level of the reactants and products
Negative
38
Is define Endergonic in terms of delta G
Low energy reactants are converted into high energy products
39
If a reaction is Endergonic what is the energy level of the reactants and products
Positive
40
If a reaction is spontaneous what does that mean
They occur on their own, no impute of energy needed
41
When or under what conditions are reactions going to be spontaneous
When there's more products and reactants
42
How is entropy related to spontaneous reactions
There will be an increase of entropy
43
Catabolic
Releases energy
44
Anabolic
Consumes energy
45
Exergonic
Δg is negative
46
Endergonic
Δg is positive
47
Degradative
Breaking down
48
Biosynthetic
Building up
49
Spontaneous
Increases entropy
50
Non spontaneous
Decreases entropy
51
What are the functions of the membrane
Cell boundary, permeability barrier ( transport control and electrical/chemical gradient), site for protein attachment/insert insertion
52
What is the major component of the membrane
Phospholipid bilayer
53
Define hydrophilic
Likes water, interacts with the water
54
Define hydrophobic
Scared Of water doesn't like water
55
What is the difference between a saturated fatty acid in an unsaturated fatty acid
Saturated is straight unsaturated is bent
56
Describe the characteristics of a membrane that only contain saturated fat fatty acids
If there are too many saturated fatty acids it will be too hard and not permeable at all
57
Describe the characteristics of a membrane that only contain fat unsaturated fatty acid
It will be too liquidy
58
What role does cholesterol play in terms of the membrane
Effect/change membrane permeability
59
What are the two general types of membrane proteins
Peripheral and intergal
60
Where are the Peripheral membrane proteins located
On the outside of the membrane
61
What are the potential activities of Peripheral membrane proteins
Enzymatic, hydrolytic, communication, signaling, recognition
62
Where are the integral membrane proteins located
On the inside of the membrane (in between phospholipids)
63
What are the potential activities of the integral membrane proteins
transportation
64
Define passive movement
No energy is required. molecules move from an area of high concentration to an area of low concentration
65
Define active movement
Energy is required movement from low to high
66
Compare and contrast passive and active movement
Passive results and dilution an active results and concentration
67
What is a solvent
Liquid normally water water
68
What is a solution
Solute +solvent
69
What is a solute
Solid
70
What are the three types of passive movement
Facilitated diffusion and simple diffusion and osmosis
71
Define diffusion
The movement of molecules from high to low
72
Define simple diffusion
Solutes move through the membrane unassistanted
73
Define facilitated. Diffusion
Solutes move through a transport proteins in the membrane
74
Compare and contrast simple and facilitated diffusion
Simple is unassisted
75
Which type of diffusion requires transport proteins
Facilitated
76
When or what point does diffusion stop
When it reaches equilibrium
77
What kind of molecules are freely diffusible
Small nonpolar and polar compounds
78
What kinds of Molecules are not able to freely able to cross the membrane
Large or charged molecules
79
Define osmosis
Water moves through the membrane unassisted high to low
80
Define hypotonic solution
Salute concentration outside the cell is lower than inside the cell
81
Define hypertonic solution
Salute concentration outside the cell is higher then inside the cell
82
Define iso tonic solution
Solute concentration outside the cell is equal to inside the cell
83
Which direction will water move when a cell is in a hypertonic solution
Into which leads to osmotic lysis
84
Which direction will water move when a cell is AN a hypotonic solution
Out which will create plasmolysis
85
Which direction will water move when a cell is in an iso tonic solution
Want because it will be equal
86
What is Osmotic lysis
The influx of water into a cell will cause the cell to swell and burst
87
Which cell structure protects against osmotic lysis
Cell wall
88
What Is plasmolysis
Efflux of water out of the cell cytoplasm shrinks and pulls away from the membrane
89
Difference between a channel protein and a carrier protein
Channel proteins allow certain molecules pass through; carrier bind and carry molecules thru
90
What is the difference between an open channel and I gated channel
Open lets anything through gated is selective
