MCAT Enzymes Review

Oxidoreductases

Kinase

Catalyze the transfer of a phosphate group (often from ATP) to another molecule

Transferases

Hydrolases

Lyases

Isomerases

Ligases

Maximum velocity of enzyme activity

v_max

Rate at which enzyme+substrate complex goes to enzyme and product

k_cat

1) substrate concentration at which half of enzyme’s active sites are full
2) measure of affinity of the enzyme for its subtrate
3) Michaelis constant

K_m

Catalytic efficiency
