10.
The diagram shown is of the polymer amylose which is important in plant energy storage. Amylose is the preferred starch for storage in plants. It makes up about 30% of the stored starch in plants, though the specific percentage varies by species. The digestive enzyme amylase is responsible for the breakdown of the starch into monomers, which can be used as a quick source of energy. What is the monomer subunit of amylose?
a)
Glucose
b)
Triglyceride
c)
Amylase
d)
Amino Acids
Reset
