QuestionAnswer
Substances that cause chemical reactions to occur faster are called Enzymes
How do enzymes work? By decreasing the amount of energy needed to activate the chemical reaction
For its function, enzymes are also known as? Catalysts
Most enzymes are ...? Proteins
What affects an enzyme? Temperature and PH
What enzyme is essential to the process of transcription? RNA
How are enzymes produced? By a cell's ribosomes
What is lactase? employed to remove lactose from milk
Cellulases and pectinases used for clarifying fruit juices
What can enzymes be made out of? Protein or RNA
coenzymes small organic cofactors
What are the 2 classes of multiple substrate reactions? sequential displacement and double displacement sequential displacement and double displacement
Multiple substrates - random sequential mechanism the order of the substrate binding and product release doesnt matter
What enzyme strategy does chymotrypsin use? covalent modification - the substrate has to be bound
Catalysts chemical agents that speed the rate of a chemical reaction without being consumed or changed
What are substrates Reactants in enzyme catalyzed reactions
Enzymes differ in _____? specificity
2 theories of active site and substrate fit, and their differences? Lock and Key model- enzyme won't change shape
3 Environmental factors that affect enzyme reaction rate Temperature pH Inhibition
Products Material resulting from the chemical reaction. Reactants undergo a change and produce the products
Inhibitors Fills the active site but does not work; it prevents the substrate from bonding with the enzyme
Denaturation Enzymes losing its shape or function
