Enzymes

Question 1

Act on many chemical groupings to add or remove H+ atoms

Answer 1

Oxidoreductases

Question 2

Transfer functional groups between donor and acceptor molecules. Kinases are specialized transferases that regulate metabolism by transfer phosphate from ATP to other molecules

Answer 2

Transferases

Question 3

Add water across a bond, hydrolyzing it

Answer 3

Hydrolases

Question 4

Add water, ammonia and carbon dioxide across double bonds or remove these elements to form double bonds

Answer 4

Lyases

Question 5

Carry out many types of isomerization, L to D, mutases, shifts of chemical groups (change direction)

Answer 5

isomerases

Question 6

Catalyze reactions in which two chemical groups are joined or lighted with the use of energy from ATP

Answer 6

Ligases

Question 7

Rate of enzyme catalyze reaction and the concentration of the substrate (equation)

Answer 7

Michael-Menten Kinectics equation

Question 8

Michaels-Menten Kinectics equation

Answer 8

V1 = Vmax [S] / {Km + [S]}

Question 9

Km refers to

Answer 9

Affinity and velocity of substrate

Question 10

Km relationship to affinity

Answer 10

Inversely

Question 11

Michaels-Menten equation demonstrates that

Answer 11

1/2 Vmax the substrate concentration is numerically equal to Km

Km = 1/2 Vmax

Question 12

Decreased Km equates to

Answer 12

High affinity (do not need a high concentration to grab)

Question 13

Increase Km equates

Answer 13

Decreased affinity (need higher concentration)
