When Do Enzymes Work Best? Flashcards
1
Q
What is an active site?
A
Has a specific shape
The part of the enzyme that the substrate molecules bind to
Specific shape is determined by the enzymes tertiary structure
2
Q
How does the enzyme work?
A
The substrate has to fit into the active site (shape has to be complementary)
If the substrate shape Doesn’t match the active site, the reaction won’t be catalysed
This means enzymes work with very few substrates
3
Q
What do enzymes work best in?
A
Optimum:
pH
Temperature
Endothermis- homeostasis
4
Q
What type of proteins are enzymes?
A
Globular proteins
