-
Enzymes are _____ that serve as _______.
They speed up or slow down _______, but always remain Unchanged.
- proteins
- Catalysts
- reactions
-
What is an active site?
where the substrate binds to the enzyme.
-
Each enzyme acts on a specific _____.
substrate
-
what is a substrate
The reactant that the enzyme will act upon
-
interaction of the enzyme and the subtrate
Induced fit
-
what fits in the Enzyme slot?
and what 2 sugars is it made up of?
- lactose
- glucose and galactose
-
if someone is lactose intolerant, they lack __________.
lactose
-
the conformation of an enzyme is maintained by interactions between various _____ ______ that compose it, and this conformation is sensitive to the changes in the enzyme's _______.
-
2 important influences of enzyme activity:
pH and temperature
-
each enzyme functions best within a certain _________ _________.
pH Range
-
enzymes in stomach like _______ environments.
Enzymes in small intestines like ______ environments.
-
catalase will increase at ____ temperatures but when it reaches boiled, it will go beyond its functional shape, so it will ______ most enzymes.
-
difference between a noncompetitive inhibitor and a competitive inhibitor.
- noncompetitive inhibitor: Binds to a place OTHER than the active site.
- competitive inhibitor: binds to the ACTIVE site of the enzyme
-
for a catalase reaction, an enzyme and a _________ unite.
substrate
-
 where's the substrate, substrate enzyme complex, & active site?
-
where do competitive and noncompetitive inhibitor go? and what do they do?
- competitive: in active site- interferes so that the enzyme and substrate can't bond.
- noncompetitive: anywhere but active site - modifies the shape so it also cant bind to the substrate
