UPTAKE OF GLUCOSE BY FUNGIA 653 It is of interest to consider the energy requirements of these animals, as indicated by their oxygen consumption. Table III lists the oxygen consumed per hour for 18 animals. The equivalent amount of glucose is also tabulated. The slope and standard error of a regression line relating the log of oxygen consumption and log wet weight is ± Although the standard error is large, the slope is significantly different from zero. The slope may be used to calculate mean oxygen consumptions at weights of 30 to 45 grams. These are, respectively, and ml. (X/hour. These are in turn equivalent to and mg. of glucose. 10 S(mg/ I) i 15 20 FIGURE 3. Rate of uptake as a function of glucose concentration. The line is the least squares regression line. Weight is 30-45 grams. oxidized per hour. At the mean rate of uptake calculated for this size range above, ambient glucose concentrations of to would suffice to provide these amounts of sugar. Furthermore, since the rate of uptake is related to size in the same fashion as is oxygen consumption, ambient concentrations of glucose in this general range should suffice to account for oxygen consumption regardless of size. The general form of the curve relating concentration and the rate of glucose tration. This should approximate a straight line. The regression line of such a plot has a slope of ± and an intercept of ± This is formally equivalent to an enzyme- catalyzed reaction and Vmax and Km (the concentration at which the velocity is half maximal) can be evaluated. Vma* is and Km is This is in reasonable agreement with the rates calculated more directly from the data. Since departures from linearity for double reciprocal plots are quite common (Neilands and Stumpf, 1958), the presentation in the text is Please note that
