Temperature And Enzymes

Question 1

define anabolic

Answer 1

building

Question 2

define catabolic

Answer 2

breaking

Question 3

how do enzymes lower the activation energy

Answer 3

enzymes provide an alternative pathway

Question 4

what is the role of catalase

Answer 4

h202 -> H20 + O2

Question 5

define cofactor

Answer 5

non protein component that is essential to the functionality of an enzyme

Question 6

what are the two types of cofactor

Answer 6

prosthetic group and coenzyme

Question 7

what is a prosthetic group

Answer 7

a permanent cofactor

Question 8

what is a coenzyme

Answer 8

temporary cofactor (often ion)
-eg Zn2+ for carbonic anhydrase
-eg Cl- for amylase

Question 9

Q10

Answer 9

rate at T + 10 degrees / rate at T

Question 10

how does pH affect the structure of a protein

Answer 10

-H+ ions can disrupt the hydrogen bonds in the secondary structure
-H+ ions can disrupt ionic interactions by altering R group

Question 11

how does temperature affect the structure of a protein

Answer 11

genetic energy causes protein to unravel

Question 12

what is the difference between competitive and non competitive inhibitors

Answer 12

competitive: compete for the same active site and binds for a period of time.
non competitive: bind to allosteric site which disables enzyme function
