Enzymes
- protein acts as a structural
components of tissue (e.g
muscle), hormones and
antibodies.
- Enzymes are all made from up of
chains of amino acids.
- Enzymes are all made from up of
chains of amino acids.
- They usally only catalyse one reaction.
- Because for the
enzyme to work,
the substance has
to fit a special
shape.
- Every enzyme has a unique shape that fits
onto the substance involved in a reaction.
- If the substance doesn't
match the enzyme shape, the
reaction won't be catalysed.
- Because for the
enzyme to work,
the substance has
to fit a special
shape.
- If the temperature is too hot, some of the bonds holing the enzyme together break. This
destroys the enzyme shape, so it won't react.
- If Ph levels are too high/low they can change shape
- Enzymes in the human body
work at 37 degrees
- Most enzymes work at Ph 7 (neutral), but Pepsin works best at Ph 2in
the stomach, well suited for the acidic condition.
- If Ph levels are too high/low they can change shape
