Enzyme Models Flashcards
What is the Induced Fit model.
The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis.
What is the Lock and Key model.
The lock and key model assumes that the active site of the enzyme and the substrate are equal shaped. It supposes that the substrate fits perfectly into the active site of the enzyme.
What is an Active site.
The region on an enzyme that binds to a protein or other substance during a reaction.
What is an Enzyme.
Enzymes are proteins that have a specific function. They speed up the rate of chemical reactions in a cell or outside a cell. Enzymes act as catalysts, they do not get consumed in the chemical reactions that they accelerate.
Which enzyme model changes shape slightly , creating an ideal fit?
Induced fit model.
Which enzyme model is meant to perfectly fit into the substrate?
Lock and Key model.
What is a substrate?
A substrate is a molecule acted upon by an enzyme. A substrate is loaded into the active site of the enzyme, or the place that allows weak bonds to be formed between the two molecules.
What happens to the enzyme when it is denatured?
The active site changes shape not allowing the substrate to bind.
