Day 2

Question 1

Most Common Quartnery Protein?

Answer 1

Hemoglobin

Question 2

Coenzymes Vs Cofactors

Answer 2

Coenzymes are organic (have carbons, such as vitaimes)

Cofactors are inorganic (no carbon, like metals)

Question 3

Fat Soluble Vitamins?

Answer 3

DEKA

Question 4

Disadvantage of too much fat soluble vitamins?

Answer 4

Fats are not excreted, get stored in fat cells

Question 5

Coenzymes and Cofactors, Their Role

Answer 5

Enzyme cannot bind to substrate without coE or coF present

Question 6

holoenzyme

Answer 6

is whole, has its cofactor or coenzyme

Question 7

apoenzyme

Answer 7

empty, does not have necessary cofactor or coenzyme

Question 8

prosthetic group

Answer 8

when enzymes basically permanently bound, i.e iron and hemoglobin

Question 9

lil hot

Answer 9

ligase, isomerase, lyase, hydrolase

Question 10

Ligase

Answer 10

joins things together (i.e DNA ligase, synthetase)

Question 11

Isomerase

Answer 11

Rearrange, change structure, shufflers (mutase)

Question 12

Lyase

Answer 12

Breaks things apart without water

Question 13

hydrolase

Answer 13

breaks things apart with water (amylase,peptidease)

Question 14

Oxidoreductase

Answer 14

promotes redox reactions (dehydrongenase)

Question 15

Transferase

Answer 15

Transfers a functional group (kinase-add phosphate groups)

Question 16

phosphorolase

Answer 16

breaks bond by adding phosphate

Question 17

pepsin

Answer 17

in your stomach, pH 2

Question 18

Body temp C?

Answer 18

37 C

Question 19

taq polymerase

Answer 19

Operates at HIGH temps (Polymerase Chain Reaction)

Question 20

Polymerase Chain Reaction (PCR)

Answer 20

Makes lots of copies of DNA at high temps (taq polymerase)

Question 21

Hill > 1

Answer 21

Cooperative Binding (i.e. hemoglobin)

Question 22

Lineweaver Burk (X, Y, Y Intercept, X Intercept?)

Answer 22

X= 1/S
Y= 1/V
Y Intercept= 1/Vmax
X Intercept= -1/Km
