Glycogen is also called as the animal starch. This carbohydrate polymer is made up of the several repeating monomer units (in thousands) of alpha D glucose. The skeletal muscles break down this glycogen into the monomer alpha D glucose units in order to generate energy, which can be used for the contraction and relaxation of the muscle filaments.
Hence, the answer is 'alpha D glucose'.
Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.
