When muscle cells have more glucose than they need for energy, they may store some of the excess as?

I think the answer is glycogen.Glycogen functions as one of the two forms of long-term energy reserves, with the other form being triglyceride stores in adipose tissue. In human body, glycogen is made and stored primarily in the cells of the liver and skeletal muscle. In the muscles it is the primary fuel the muscles use for energy production. 

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
