Use the mark scheme to improve your answer
Write your improvements in red pen
You need two pros and two cons for screening
You need a conclusion statement
It needs to be clear, with correct spelling and
grammar.
Explain how a stent would be used
to treat this condition (5 marks)
Mark Scheme
Exemplar Answer
The stent keeps the artery
open, this allows more blood to
flow through. The stent is
inserted into the blood vessels
using a balloon. The balloon is
inflated to open the artery and
the stent remains in place to
keep the artery open.

Which is the best answer?
A. pH changes the shape of the active site
on an enzyme molecule, stopping it fitting
with the substrate molecule.
B. pH changes the shape of the reaction site
on a substrate molecule, stopping it
fitting with the enzyme molecule.
C. pH changes the shape of the enzyme
molecule, preventing it reacting with the
substrate molecule.
More than one is correct, but which is the best?
How are enzymes involved in digestion?
• The enzyme amylase is produced in the salivary glands, the
pancreas and the small intestine. This enzyme catalyses the
breakdown of starch into sugars in the mouth and small intestine.
Protease enzymes are produced by the stomach, the pancreas and
the small intestine. These enzymes catalyse the breakdown of
proteins into amino acids in the stomach and the small intestine.
Lipase enzymes are produced by the pancreas and small intestine.
These enzymes catalyse the breakdown of lipids (fats and oils) into
fatty acids and glycerol in the small intestine. The liver produces
bile, which is stored in the gall bladder before being released into
the small intestine. Bile neutralises the acid that was added to food
in the stomach. This provides alkaline conditions in which enzymes
in the small intestine work most effectively.

Using stem cells
In 2012 scientists in America were able to re-program embryonic stem cells
to form into cartilage cells to produce a replacement human outer ear.
The ear needed a blood supply to grow, so they implanted it under the skin
of a laboratory mouse. The ear was eventually transplanted onto the head
of a 9 year old boy who had lost his ear in a car accident and risked
deafness. The boy is now able to hear normally and lead a normal life.
Stem cells obtained in
this way often result in
the destruction of the
developing embryo.
Embryonic stem cells
are the most useful of all
stem cell types as they
can turn into any type of
body cell.

you’re still wrong!
