important Flashcards
1
Q
enthalpy
A
amount of energy
2
Q
exergonic reactions
A
- Energy of Reactants more than products; change in gibbs is negative
- Exothermic
- Spontaneous
- Energy input not required
- Change in gibbs is negative
- Energy released
3
Q
endergonic reactions
A
- Energy of Products more than reactants ; change in gibbs is positive
- Endothermic
- Non spontaneous
- Energy input required
- Change in gibbs is positive
- Energy absorbed
4
Q
change in gibbs free energy in exergonic
A
negative
5
Q
spontaneous reaction
A
exergonic
6
Q
energy of products more than reactants
A
endergonic
7
Q
which reaction releases energy
A
exergonic, exothermic
8
Q
are enzymes used up inna reaction
A
no
9
Q
enzyme kinetics
A
rate at which an ezyme catalayses a reaction
10
Q
when is vmax lowered
A
in non competitive inhibtion as number if available enzymes are decreased due to change in affinity
11
Q
when does km not change
A
non comp inhibtion
12
Q
what does km depend on
A
affinity
13
Q
what does vmax depend on
A
enzyme concentration
14
Q
what increases km
A
compeitive inhibtion
15
Q
when does vmax stay the same
A
compeitive inhibtion
