The mitochondria is responsible for respiration, but glycolysis occurs in the cytoplasm of the cell. The Krebs cycle and electron transport both occur in the mitochondria of t â¦ he cell. Cellular aerobic respiration occurs within the mitochondria. Cellular respiration occurs in the mitochondria of a cell.
Glycolysis is the first stage of aerobic (and anaerobic) respiration. It takes place in the cytoplasm of the cell. In glycolysis (âglucose breakingâ), ATP is used to split glucose molecules into a three-carbon compound called pyruvate.This splitting produces energy that is stored in ATP and a molecule called NADH. Unlike the rest of aerobic respiration, which takes place in the mitochondria, glycolysis takes place in the cytoplasm of the cell. 2  Unlike the rest of aerobic respiration, glycolysis does not require oxygen.
