The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes place in the cytoplasm. read more

Respiration starts when glucose enters the cell membrane. Glucose changes into pyruvate through the process of glycolysis in the cell's cytoplasm. Glycolysis occurs in 10 basic steps when carbon, hydrogen and oxygen atoms interact with phosphorus in the cell, according to State University of New York. read more

Cellular respiration occurs in three main steps. The first step takes place in the cytoplasm of the cell. The last two steps take place in the mitochondria(or if cellular respiration is taking place inside of a plant then the last two steps would take place in the chloroplasts) of the cell. read more
