Chapter 15 Enzymes
- An Enzyme is an organic
Catalyst which speeds up
or slows down the
reaction without itself
being used up (becoming
part of the reaction.)
- Introduction
- Metabolism= the sum of all the
chemical reactions that take
place in an organism.
- Catabolic reaction
- When a more complex
miomolecule is broken
down to simpler forms
and so releases energy.
- respiration
and
diffusion
- respiration
and
diffusion
- When a more complex
miomolecule is broken
down to simpler forms
and so releases energy.
- anabolic reaction
- converts simpler
molecules into more
complex (energy is
consumed)
- photosynthesis
conversion
of
amino
acids
into
protein.
- photosynthesis

- Metabolism= the sum of all the
chemical reactions that take
place in an organism.
- sources of energy
- solar energy
- primary
source of
energy for
life.
- producers use it to form the
chemical bonds of carbs and
other biomolecules. This is
carried out through
photosynthesis.
- Autotrophs:
they make
their own food
- primary
source of
energy for
life.
- Cellular energy
- sources of energy
that are capable of
being released by
reactions within
the cell
- each
organism
breaks
down
biomolecules
in
the
process
of
respiration
- heterotrophs:
cannot make
their own food
- sources of energy
that are capable of
being released by
reactions within
the cell
- solar energy
