It depends on what type of cells you're talking about. Assuming that you are talking about humans, the process is called cellular respiration. The first step is glycolysis, where glucose is split into two molecules of pyruvic acid. This occurs in the cytoplasm of the cell. This pyruvic acid then enters the mitochondria of the cell and goes through a process called the Kreb's cycle (or sometimes the Citric Acid cycle.) The energy is taken from the pyruvic acid and passed on to other molecules (NADH+H+, fADH2). These molecules then enter the final step of the respiration process, the electron transport chain. The energy passes through a series of proteins, drawn by the electronegativity of Oxygen. Ultimately, the energy is packed into a molecule called ATP (Adenosine Triphosphate) and this is the primary source of energy for cellular functions.

What are organelles that break down sugar to produce energy?

The breakdown of sugar (mainly glucose) is called glycolysis and occurs in the cytoplasm of a cell. The product of glycolysis is pyruvate, which is used to make ATP energy by the Krebs Cycle in the mitochondria.
