Enzymes Flashcards
1
Q
Key words for Enzymes
A
- Biological Catalysts
- Globular proteins
- Substrate binds to SPECIFIC active site
- Enzyme substrate complexes form
- Denaturing when pH or temp varies
- Substrates and enzymes must collide with correct orientation and speed for reactions to occur
- Tertiary structure determines shape of active site
2
Q
What is an enantiomer?
A
- Optical isomers of each other but differ in ability to in biological activity
3
Q
What is an active enatiomer?
A
- An enantiomer rotated correctly so complementary to active site
4
Q
Drugs and enantiomers?
A
Site where drug binds to biomolecule can only accept 1 orientation is stereoselective to enantiomers
