Salivary amylase is an enzyme found in the mouth. it breaks down starch into sugars. why will salivary amylase not break down proteins?

a. the enzyme is the wrong substrate for proteins.
b. only sugars have the correct shape to activate the enzyme.
c. proteins will not fit into the active site of the amylase enzyme
d. proteins do not have the proper active site for the enzyme to work on them

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
