Enzymes
- Cells have
thousands of
different chemical
reactions going on
inside them all the
time
- Respiration
- Respiration releases
energy for cells from
glucose. This can be aerobic
respiration, which needs
oxygen, or anaerobic
respiration, which does not.

- Photosynthesis
- Photosynthesis is a process used by plants and other
organised to convert light energy, normally from the Sun, into
energy that can be later released to fuel the organisms
activities.

- Protein Synthesis
- The production of
proteins in a cell
using base pairs.
- The production of
proteins in a cell
using base pairs.
- These reactions
need to be
carefully
controlled- to get
the right amounts
of substance and
keep the organism
working properly.
- You can usually make a reaction happen more quickly by
raising the temperature. This would speed up the useful
reactions but also the unwanted ones too... not good.
There's also a limit to how far you can raise the
temperature inside a living creature before the cells start
to get damaged,
- So living things
produce Enzymes,
which act as biological
catalysts. A catalyst is
a substance that
speeds up a reaction,
without being changed
or used up in the
reaction itself.
- Enzymes reduce
the need for high
temperatures
and we only have
enzymes to
speed up the
useful chemical
reactions in the
body.
- Every different biological reaction has its own enzyme designed especially for it.
- Each enzyme is coded for by a different gene,
and has a unique shape, which it needs to do its
job.
