enzymes Flashcards
1
Q
role of enzymes
A
build larger molecules into smaller ones, breakdown larger molecules into smaller ones
2
Q
enzymes are biological…
A
catalysts + protiens
3
Q
why is body temp 37 degrees?
A
37 is too cold for reactions so enzymes speed them up to keep us alive
4
Q
how enzymes work
A
- enzyme acts on a substrate to speed up reactions
- active site is the region on an enzyme that binds to a substrate during a reaction
- a collision with enough energy has to occur between enzyme + substrate for a reaction
5
Q
lock and key theory
A
enzyme binds to active site, enzyme-substrate complex, products leave active site + enzyme unchanged
6
Q
key statements
A
- enzyme active sites are a specific shape for one substrate
- active site is a complimentary shape for the substrate
