in the human body?
answer

Amylase is the enzyme involved in the
breakdown of starch into smaller
molecules during the digestion process

mmcl2003

31 Why must starch be broken down to smaller
molecules during the process of digestion?
answer

Starch molecules are very large and
must be broken down until they are
small enough to pass through the gut
wall into the bloodstream to be used in
digestion
mmcl2003

14

How does the structure of starch relate to
glucose?
answer

Starch is a polymer molecule made from
many glucose monomer units joined
together

mmcl2003

13

Why is starch a condensation polymer?
answer

When many glucose molecules link
together to form the polymer starch they
join with the loss of water molecules

mmcl2003
