- Fructose and glucose are both monosaccharides, but the body metabolizesthese sugars differently. For example, glucose stimulates insulin releasefrom the pancreas (see section 28.4); fructose does not. Moreover, insulinstimulates leptin release. Finally, fructose is more likely than glucose tobe converted to fat. Use this information to propose an explanation for thecorrelation between the skyrocketing consumption of high fructose cornsyrup since 1970 and the rise in obesity during the same period.arrow_forwardMatch the following: a.

- Applying Math Use Percentages GLUCOSE LEVELS Calculate how much higher the blood sugar (glucose) level of a diabetic is before breakfast when compared to a nondiabetic before breakfast. Express this number as a percentage of the nondiabetic sugar level before breakfast. 3.5 Diabetic 3.0 - Nondiabetic 2.5 2.0 1.5 1.0 Solution 0.5 1 This is what you know: nondiabetic blood 1 2 3 45 6 sugar at 0 h = 0.85 g sugar/L blood • diabetic blood sugar at 0 h = 1.8 g sugar/L blood Hours after breakfast How much higher is the glucose level of a diabetic persor than that of a nondiabetic person before breakfast? This is what you need to find out: • Find the difference in glucose levels: 1.8 g/L – 0.85 g/L = 0.95 g/L 3 This is the procedure you need to use: • Use this equation: difference between values nondiabetic value X 100% = percent difference • Substitute in the known values: 0.95 X 100% = 112% 0.85 • Before breakfast, a diabetic's blood sugar is about 112 percent higher than that of a…arrow_forwardShortly after a typical meal, your blood glucose will rise from its fasting level of 4.4mM to 6.6mM.
