The graph shows that during 40 days of starvation, the concentration of glucose decreases rapidly while the concentration of ketone bodies increases. This is indicative of the body shifting from glucose as its primary energy source to utilizing ketone bodies. The concentration of fatty acids also increases, but not as rapidly as ketone bodies. Therefore, X = ketone bodies, Y = glucose, and Z = fatty acids.
