Sometimes secondary active transport transports things in the same direction as the sodium ions.  For example glucose from the intestine and amino acids are transported this way.  In other cases sodium flows into a cell to provide energy to remove other ions such as [[Essential Ion and Compound Balance and Homeostasis - Anatomy & Physiology#Acid / Base|'''H⁺''']] and [[Essential Ion and Compound Balance and Homeostasis - Anatomy & Physiology#Calcium|'''Ca²⁺''']]
