12 Questions
What is the role of enzymes in a reaction?
Decrease the activation energy
Under what condition would an enzyme be saturated?
High substrate concentration
What does the Michaelis constant (Km) represent?
The substrate concentration needed for 1/2Vmax
How do changes in pH affect enzyme activity?
Decrease enzyme activity
Which structure do proteins need to fold into to function properly?
Tertiary structure
What happens to enzyme function at very high substrate concentrations?
Enzymes reach Vmax
What is the main purpose of acid/base catalysis in enzymes?
To make reactions go faster by proton transfer
Where do enzymes lower the activation energy of a reaction?
At the transition state
What model explains the phenomenon where enzymes and substrates change their shape slightly to bind together tightly?
Induced-fit Model
What type of catalysis involves charged molecules or metal ions to stabilize big positive or negative charges?
Electrostatic Catalysis
In enzyme-substrate specificity, what is responsible for determining the specificity of an enzyme?
