(solution) Macronutrients are usually regulated by fostering the oxidation of fuels

Macronutrients are usually regulated by fostering the oxidation of fuels that are most abundant at the time and/or that cannot be stored. This means that most tissues oxidize glucose after a meal (post-prandial state) and oxidize fatty acids in the starved state.a. Describe some of the most important regulatory mechanisms that underlie the use of glucose but not fatty acids in the postprandial state AND the use of fatty acids but not glucose in starvation.b. Are there times when the body’s metabolism is changed to promote oxidation of both glucose and fatty acids at the same time? If so, what mechanisms play a role in allowing this to occur?
