Cellular respiration:

1. It is the process in which a series of metabolic reactions occur in the mitochondria of organisms.
2. In this, glucose is broken down to produce energy in the form of ATP in the presence of oxygen.
3. Waste and carbon dioxide are released as by-products.
4. Glycolysis is the first step in cellular respiration that occurs in the cytoplasm within the mitochondria.
5. Glycolysis is the process in which glucose six-carbon sugar molecule is broken down into 3C molecules to generate cellular energy.
