enzymes Flashcards
1
Q
enzymes are a
A
catalyst
2
Q
what are they and what do they do?
A
protiens that speed up reactions
3
Q
what does it cause molecules to do?
A
to form or break apart
4
Q
the molecule that the enzyme will catalyze is called a?
A
substrate
5
Q
what are the defintion of lock and key model?
A
substrate = key
enzyme = lock
active site = keyhole
6
Q
protease
A
protien
7
Q
amylase
A
starch
8
Q
lipase
A
lipids
9
Q
what pH and temp do enzymes work best at
A
pH= 7
temp= 37
10
Q
what happens at high temp
A
enzymes get denatured and break bonds
11
Q
what happens at low temp
A
Low kinetic energy (particles move more slowly so less substrate and enzyme collisions)
