Enzymes are proteins that catalyze (speed up) chemical reactions in living organisms.
What are the two major classes of enzymes?
The two major classes of enzymes are metabolic and digestive enzymes.
What is the active site of an enzyme?
The active site of an enzyme is the region that binds to the substrate and catalyzes the chemical reaction.
What is an inhibitor of an enzyme?
An inhibitor is a molecule that binds to an enzyme and decreases its activity.
What is a coenzyme?
A coenzyme is a non-protein compound that is required for the function of certain enzymes.
What is the difference between an enzyme and a catalyst?
An enzyme is a type of catalyst that is produced by living organisms, while a catalyst is any substance that increases the rate of a chemical reaction.
What is the lock and key model of enzyme function?
The lock and key model proposes that the shape of the enzyme and substrate are complementary and fit together like a lock and key, allowing the reaction to occur.
What is denaturation of an enzyme?
Denaturation is when an enzyme loses its shape and function due to high temperatures, extreme pH, or other environmental factors.
What is an allosteric enzyme?
An allosteric enzyme is an enzyme that has multiple binding sites and can be regulated by molecules that bind to sites other than the active site.
What is the Michaelis-Menten equation?
The Michaelis-Menten equation is a mathematical model that describes the relationship between an enzyme and its substrate. It is useful for determining the kinetics (rate) of an enzyme-catalyzed reaction.
What is the role of enzymes in metabolism?
Enzymes play a critical role in all metabolic pathways by catalyzing the chemical reactions that convert one molecule into another.
What is the optimal pH for most enzymes?
The optimal pH for most enzymes is around 7, which is neutral.
What is an enzyme substrate complex?
An enzyme substrate complex is the intermediate formed when the enzyme binds to the substrate before the reaction occurs.
What is the role of enzymes in digestion?
Enzymes break down food into smaller molecules that can be absorbed by the body. Examples include amylase, which breaks down carbohydrates, and lipase, which breaks down fats.
What is the role of enzymes in DNA replication?
Enzymes such as DNA polymerase catalyze the synthesis of new strands of DNA during replication.
