 Carbon monoxide also combines with hemoglobin and myoglobin with the help of facilitated diffusion just as it is in oxygen but the rate at which they react differs from one another.Carbon monoxide has a dissociation velocity which is 100 times less than that of oxygen; its affinity for myoglobin is 40 times higher and 250 times higher for hemoglobin, compared to oxygen.Glucose is a six-carbon sugar that provides energy needed by cells.
