Enzymes Flashcards
Enzymes
Are biological catalyst which is made of protein
Catalyst
A substance that speeds up the rate of a chemical reaction without its self taking part in the reaction
Substrate
Substances on which an enzyme acts
Product
The substance formed when an enzyme reacts with a substrate
Buffer
A solution which can maintain a pacific pH
Active site
The region of the enzyme that binds with the substrate
Induced fit
When the enzyme active site changes shape slightly to fit the substrate
Activation energy
The energy needed to start a chemical reaction
Optimum activity
Enzymes working at its most efficient and best rate
Denatured enzymes
The change in the structure of the active site preventing the enzyme from bonding with a specific substrate
Rate of activity
The amount of product produced per unit time
Bioprocessing
Use of enzyme-controlled reactions to produce a product
Bioreactor
A vessel used to carry out enzyme controlled reactions to produce a product
Batch processing
Fixed amount of nutrients added at the beginning and emptied at the end of the production
Immobilised enzymes
Enzymes that are fixed in inert material
