Enzymes Flashcards
What happen if you raise the tempreture
Speed up useful and negative reactions (not good)
What do enzymes reduce the need of
High temperatures
Why do have enzymes
To speed up useful chemical reactions in the body
Enzymes are all …..
Proteins
What are enzymes made up off?
Chains of amino acids
What do proteins and catalysts act as?
Structural components of tissue (eg muscle), hormones and antibodies
Why do enzymes have special shapes
So they can catalyse reactions
What happens if the enzymes get too hot?
The bonds holding the enzymes together break
If the enzyme no longer work, what are they said to be?
Denatured
What tempreture to enzymes work best?
37°c
What happens if the enzymes PH is not correct?
Interferes with the bonds holding the enzyme together and so therefore will become denatured
What PH do most enzymes work best
PH 7
What is PEPSIN and where is it found
Enzyme used to break down proteins and is found in the stomach
What PH scale does peeps in work best in?
PH 2 (well suited to acidic conditions)
What is an enzyme
A biological catalyst produced by living things
