All of the following metabolic changes would occur if breakfast is skipped following an overnight fast EXCEPT:
a. degradation of liver glycogen
b. fatty acid are oxidized for energy
c. muscle protein breakdown
d. degradation of muscle glycogen
e. gluconeogenesis in liver
Ans. (b) fatty acids are oxidised for energy
Expalination: Glucose is the most easily convertable molecule into ATP and glucose is produced from stored glycogen in liver and muscle during short term fasting like skipping breakfast. It occurs during shortage of glucose in blood. Gluconeogenis is the formation of glucose from non-carbohydrate sources. It occurs during glucose depletion in blood (fasting). If glycogen is depleted then degradation of muscle protein take place. Further starvation (extreme starvation for long duration) will induce fatty acid oxidation to release energy. Hence, normal short period fasting will not induce oxidation of fatty acids.
