A

Non- spontaneous

21
Q

Delta G = 0

A

Equilibrium

22
Q

Exergonic

A

Rxn generates energy
-delta G

23
Q

Endergonic

A

Rxn Requires input of energy
+ delta G

24
Q

Delta G of atp hydrolysis

A

-12 kcal/mol

25
Q

Active site

A

Where substrate binds

26
Q

Almost Eric site

A

Binding site for structural inhibitors to bind

27
Q

Zymogen

A

In active version of a protein

28
Q

Proteolytic clevage

A

Cutting of protein mostly for activation

29
Q

Competitive inhibitors

A

Binds to active site
Vmax no change
Km increased (curve shifts right)

30
Q

Non-competitive inhibitors

A

Reduced catalytic activity but not active site shape
Vmax reduced
Km unchanged

31
Q

Uncompetitive inhibitors

A

Binds to allosteric site of enzyme substrate complex.
Vmax reduced
Km decreases (curve shifts left)

32
Q

Mixed inhibitors

A

Allosteric site binding for ES OR Just E
Enzyme alone: km increases vmax decreases
Es acts like uncompetitive

33
Q

Line weaver burk y intercept

A

1/Vmax

34
Q

Lineweaver burk x intercept

A

-1/Km

35
Q

RNA polymerase I makes

A

rRNA

36
Q

RNA Polymerase II makes

A

MRNA

37
Q

RNA Polymerase III makes

A

TRNA
