19
Q

Enzyme which adds an inorganic phosphate to a substrate without using ATP.

A

isomerase

23
Q

A type of isomerase which moves one group to another part in the same chemical compound.

A

mutase

24
Q

An enzyme that catalyzes the TRANSFER of a functional group from one molecule to another.

A

transferase

25
Q

An enzyme that catalyzes the JOINING of two molecules.

A

ligase

26
Q

Refers to the maximum velocity of a reaction and is proportional to enzyme concentration.

A

Vmax

27
Q

The substrate concentration required to reach 1/2 Vmax.

A

Kmax

28
Q

Kmax aka?

A

Michaelis-Menten constant

29
Q

Substance which slows down the rate of reaction of any enzyme.

A

inhibitor

30
Q

What are the three ways of enzymatic regulation?

A

Non- competitive inhibition
Competitive inhibition
allosteric regulation

31
Q

Is competitive inhibition reversible or irreversible?

A

reversible

32
Q

Is non-competitive inhibition reversible or irreversible?

A

irreversible

33
Q

What happens to the Vmax in competitive inhibition?

A

Does not change

34
Q

What happens to the Vmax in non-competitive inhibition?

A

Reduces Vmax

35
Q

Will increasing the substrate affect the activity of the non-competitive inhibitor?

A

No, will not affect.

36
Q

The enzyme always binds to a site other than the enzyme’s active site. Competitive or non-competitive?

A

Non- competitive inhibition

37
Q

An enzyme’s activity is regulated by binding an effect or molecule at the enzyme’s allosteric site (a site other than it’s active site).

A

Allosteric regulation

38
Q

Effectors that enhance the protein’s activity are referred to as?

A

Allosteric activators

39
Q

Effectors that decrease the protein’s activity are called?

A

Allosteric inhibitors
