the diagram shows the part of a cell which carries out aerobic respiration. what is it called?

The part of a cell that carries out aerobic respiration is called the mitochondrion (plural: mitochondria). It is often referred to as the powerhouse of the cell because it produces the majority of ATP through the processes of the Krebs cycle and the electron transport chain inside its membrane structures. Aerobic respiration involves the breakdown of glucose with oxygen to produce energy, and this mainly takes place in the mitochondria of eukaryotic cells.
