Question

animals also make polysaccharides. excess sugar in animals is stored as glycogen, which is sometimes called animal starch. each large glycogen molecule is formed by many glucose monomers linked together. these long chains of glucose form many branches. glycogen plays an important role in regulating blood sugar: when glucose levels in blood are low, glycogen is broken down by the body to provide glucose. in the muscles, glycogen is also broken down to release energy to help with muscle contraction. what are the functions of glycogen? select all that apply. glycogen helps move food through the digestive tract. blood sugar levels decrease when glycogen is used to make glucose. glycogen provides energy for muscle contraction. excess sugar is stored as glycogen.

Explanation:

Answer:

Blood sugar levels decrease when glycogen is used to make glucose.
Glycogen provides energy for muscle contraction.
Excess sugar is stored as glycogen.
