Large intestine
1. Hydrolysis This is when enzymes break down
2. Condensation a molecule to create water
This is when enzymes are used to
build up molecules.
What does each part do? Salivary glands/mouth
These glands produce amylase, which
breaks down starch into maltose. They are
found in the…

these can link together to make a polymer
because of this principle; digestion is able
to take place.
(Do not refer to it as the monomers
principle in the exam that is done to help
you understand.)
Monomers principle in carbohydrates. Monomers have a specific name when
their principle is…

The break down of starch. This diagram shows the break down
of polysaccharides into a
disaccharide and monosaccharide.
The process follows as a hydrolysis
reaction all the way through until
only glucose molecules remain. The
glucose molecules are then used in
respiration and used to make other
substances used in…

Structure of an amino acid.

And the formation of a peptide bond
with the production of water.

Primary structure of a protein. The amino acids link together in a reaction
called polymerization. The links are called
Secondary structure of a protein. The secondary structure is when the
polypeptide chains…

they don't work. Call it a complimentary
shape when describing.
Induced fit model This is the idea that a substrate has a
similar shape but it is not exact. The
substrate is forced into the active site and
a strain is put on it breaking the molecule.
Factors affecting the…

1. First the cells must be
homogenate to break the membranes and
free the organelles
2. The homogenate is then filtered
to remove large bits of debris.
3. The filtered homogenate is put in
a centrifuge to remove any last bits of
membrane. The supernatant is poured off
and the…

potential is determined by the number or
particles dissolved into the water). Pure
water has a water potential of 0, after
that the more molecules dissolved into the
water the lower the number ie -600. Also
if there was a solution with a water
potential of -600 with a semi…




thankyou -helped a lot

Anisa -Team GR


I rate it 5 star its relly useful :)

Anisa -Team GR

btw hellman try add more words to your glossary 



lol ok
