Well, skeletal muscle cells basically want to contract skeleton muscle tissue and to contract those active MIT and filaments. What must happen is we have to have ATP. And so the predominant role that glycolysis plays in skeleton muscle cells is to actually form generate those ATP molecules. But how exactly is glycolysis actually regulated by these skeleton muscle cells? This will be the focus of this lecture. So there are three regulatory points in glycolysis and these three regulatory points are actually enzymes.
