Enzymes Flashcards
Living organisms use thousands of different enzymes to
Drive consecutive series of chemical reactions
Series of chemical reactions known as _ which maintain life
Metabolic pathways
All enzymes are based on _ molecules
Protein
Function of each type of enzyme depends on _
Shape of molecule
All enzymes work through a mechanism called the _ model
Lock-and-key
Each enzyme able to handle specific set of raw materials known as a _
Substrate
Enzyme protein is lock because contains zone called _
Active site
Active site shaped in a way which allows molecules of substrate (key) to _
Bind to it
When substrate molecules link to active site, _ is triggered
Chemical reaction
Chemical reaction alters _ of the substance
Chemical properties
Anabolic enzymes convert two _ into _
Substrate chemicals
Single product
_ enzyme break a single substrate chemical into multiple products
Catabolic
Active site is specific to
Particular substrate
When inserted, substrate molecules form _ triggering chemical reaction
Temporary links with enzyme
After substrate released, active site is _
Ready to receive new substrate
