enzymes Flashcards
1
Q
what do enzymes act as?
A
catalysts
2
Q
where do reactions occur on an enzyme
A
reactions happen on the active site
3
Q
what is an enzymes active site complementary to
A
an enzymes active site is complementary to the substrate they break down (molecule)
4
Q
why are active sites important
A
active site is where reaction occurs with a lower activation energy
5
Q
why can enzymes be described as stereospecific
A
they break down a single enantiomer and will have no effect on the other optical isomer
6
Q
what 2 factors can cause enzymes to denature
A
- temperature
- pH
7
Q
explain how enzyme inhibition works
A
the drugs bind to the active site of an enzyme by having a similar shape to the substrate
this prevents the substrate binding to the active site
