Hemoglobin is the oxygen-carrying component in red blood cells.  Hemoglobin is a protein that has an iron molecule. Aside from red  blood cells, there are white blood cells, â¦ which also are important  components of the blood.aking the world better, one answer at a time. In order for cellular respiration to take place, mitochondria must have oxygen. Mitochondria are the building blocks of the cell, and the cell cannot survive without it.
Although glycolysis requires two ATPs, the reactions produce four ATP, two NADH, molecules that are used to drive ATP synthesis in the mitochondria and two pyruvate molecules. Although glycolysis doesnât require oxygen, the fate of the pyruvate molecules depends on whether oxygen is present. If oxygen isnât available, the pyruvate is converted to lactate, and no additional ATP is produced from this conversion. If oxygen is present, the pyruvates are transported into the mitochondrial matrix.
