controls traits protein production
34
New cards
dehydration synthesis
to join molecules together by removing the water
35
New cards
removing water makes a molecule
complex
36
New cards
hydrolysis
to add water to spilt a molecule apart
37
New cards
adding water to a molecule makes it
simple

protein catalysts
40
New cards
can enzymes be reused
yes
41
New cards
what do enzymes do to molecules
break apart and put together molecules
42
New cards
most enzymes end in
ase

New cards
substrate is
the molecule that a enzyme if working on
44
New cards
product is
the molocule(s) created by an enzyme
45
New cards
denaturing enzymes
when extreme conditions cause the enzyme to change shape
46
New cards
what changes shape when an enzyme denatures
the active site
47
New cards
why is it a problem that the active site changes shape
the nutrients will no longer fit
48
New cards
what happens to an enzyme when the temperature is too hot
it denatures
49
New cards
what happens to an enzyme when the temperature is too cold
it slows down

what is the ideal pH for enzymes
neutral
52
New cards
what happens to an enzyme when the pH is too basic
it denatures
53
New cards
what happens to an enzyme when the pH is too acidic
it denatures
