D) gluconeogenesis.

Question

Quizplus · Accepted Answer

The nutritional alteration most frequently encountered in the hospitalized patient is protein-calorie malnutrition.The respiratory quotient (RQ)is equal to the VCO₂ divided by the VO₂.Fat, protein, and carbohydrates each have a unique RQ; thus, RQ identifies which substrate is being preferentially metabolized and may provide target goals for calorie replacement.This process of manufacturing glucose from nonglucose precursors is called gluconeogenesis.Gluconeogenesis is carried out at all times, but it becomes especially important in maintaining a source of glucose in times of increased physiologic need and limited supply.Fat is used as a source of energy.
