Chapter 8; Enzymes Flashcards
1
Q
Define Enzyme
A
Biological Catalyst (speeds up chemical reactions)
2
Q
Law of Conservation
A
Energy cannot be created or destroyed, but transformed from one type to another
3
Q
Entropy
A
Measure of disorder (loss of E) H= G+TS
4
Q
H =
A
Enthalpy (total heat) of total Energy (E)
5
Q
G=
A
Free Energy
6
Q
S =
A
Entropy (unusable E)
7
Q
T =
A
Absolute temp. in Kelvin (K)
8
Q
Exergonic
A
- E. Liberated
- not fast
- free E change
9
Q
Endergonic
A
- NOT spontaneous
- Requires ADDITION of free energy
10
Q
Catalyst
A
Speeds up chem. reaction w/o being consumed by reaction
11
Q
Enzyme
A
Protein catalyst in living cells
12
Q
Ribozymes
A
RNA molecules w/ catalytic properties
13
Q
Activation Energy
A
Initial E input to start reaction
14
Q
Strain Bonds
A
easier to achieve transition state
15
Q
Lowering activation E (x3)
A
- Strain Bonds
- Position Reactants
- Change local environment
