Enzymes Flashcards
What is an anabolic reaction?
A reaction that builds up molecules
What is a catabolic reaction?
A reaction that breaks down molecules
What is metabolism?
A combination of anabolic and catabolic reactions
What is a catalyst?
A substance that speeds up a reaction without undergoing permanent changes to itself.
What is a metabolic pathway?
A series of enzymes controlled reactions.
How to enzymes speed up reactions?
By lowering the activation energy
A pocket on the surface of the enzyme is called an?
Active site
The active site fits molecules called?
Substrates
Substrates and active sites must be what in order to fit together?
Complementary
Enzymes ad substrates form what?
An enzyme substrate complex
what is the hypothesis called when the active site and the substrate are complementary?
Lock and key hypothesis
Name the other hypothesis apart from the lock and key hypothesis?
Induced fit hypothesis
What happens to the enzyme in the induced fit method?
The enzymes changes shape so that the active site fits closely around the substrate.
