Question 1
1.
Put the process of gelatinization in order from what you remember from the videos last weekend.
the starch molecules become a tangled mess
the starch granules swell with all the water it is absorbing
water gets between the starch molecules and forms hydrogen bonds with the starches
You finish making pudding.
heat breaks the hydrogen bonds between starch molecules
Heat up starch in water
the starch molecules burst because of all the water it absorbs
Question 2
2.
A hydrogen bond is
the bond between the oxygen and hydrogen in one water molecule
the bond between oxygen and hydrogen in two different water molecules
the bond between two hydrogens in one water molecule
the bond between two hydrogen atoms in two different water molecules
Question 3
3.
compared to the bonds inside the molecules, hydrogen bonds are
weak
strong
about the same
