What is a substrate

Answer 12

The reactants

Question 13

What are cofactors

Answer 13

Non-protein components

Question 14

What is the role of a cofactor

Answer 14

To assist enzymes in performing their chemical reaction

Question 15

What are the two types of cofactors

Answer 15

Coenzymes and metal ions

Question 16

What are coenzymes

Answer 16

Large, complex organic cofactors

Question 17

How are coenzymes used?

Answer 17

Not tightly bound, can be used by multiple enzymes

Question 18

What are metal ions?

Answer 18

Small, simple inorganic cofactors

Question 19

How are metal ions used

Answer 19

Usually tightly bound, semi-permanent component of the enzyme.

Question 20

What are the “things” that can impact enzyme activity

Answer 20

Presence/absence of cofactors; temp.; pH; presence of inhibitiors; substrate concentration

Question 21

What effect does desaturation have in enzyme activity?

Answer 21

Enzyme unfolds, active site loses shape, activity decreases

Question 22

What does desaturation mean?

Answer 22

The enzyme isn’t its original state

Question 23

What are the two types of inhibitors

Answer 23

Competitive and non competitive

Question 24

How does a competitive inhibitor work?

Answer 24

Resembles the substrate (external regulation)

Question 25

Why does a competitive inhibitor bind at the active site?

Answer 25

To block the substrate access

Question 26

How does a competitive inhibitor decrease enzyme activity?

Answer 26

It blocks it

Question 27

How does a no competitive inhibitor work?

Answer 27

Doesn't resemble the substrate (internal regulation)

Question 28

Where does a non competitive inhibitor bind? Why does it bind here?

Answer 28

At the allocate tic site causing the active site to change shape

Question 29

What effect does inhibitor binding to the allosteric site have on the active site?

Answer 29

Changes shape so substrate can no longer bind

Question 30

In feedback inhibition what does the inhibiting?

Answer 30

The final product of a biochemical pathway

Question 31

How does the inhibitor work?

Answer 31

To prevent its own production

Question 32

What effect does saturation have on enzyme activity?

Answer 32

As you increase s.c. More products can be generated

Question 33

What does saturation mean?

Answer 33

Refers to having more substrates than available active sites
