Answer:
The energy released in the aerobic phase of cellular respiration in the mitochondria (in the form of ATP) is significantly higher than the energy released in glycolysis.
Step-by-step explanation:
During glycolysis, which occurs in the cytoplasm of cells, glucose is broken down into two pyruvate molecules, yielding a net of only 2 ATP molecules. This is a relatively small amount of energy compared to the amount of energy that can be generated during the later stages of cellular respiration. In contrast, the aerobic phase of cellular respiration occurs in the mitochondria and involves the breakdown of pyruvate (which was produced during glycolysis) through a series of chemical reactions known as the Krebs cycle, followed by the electron transport chain. This process results in the production of a net of about 28 to 30 ATP molecules per glucose molecule, which is significantly more energy than is produced during glycolysis. Overall, cellular respiration is a highly efficient process for generating energy in cells, with the bulk of the energy being produced during the aerobic phase in the mitochondria.
