Exam 5: Macronutrient Metabolism

Moderate physical activity provide benefits as great, if not greater, __________.

During anaerobic exercise, lipid becomes the sole macronutrient contributor to ATP.

Compared to lipid oxidation, carbohydrate oxidation generates about __________% greater energy per unit oxygen consumed.

In the transition from rest to moderate exercise, __________ supplies almost all of the energy.

If energy intake falls below total energy expended during intense training, even augmented protein intake above recommended values may fail to maintain proper nitrogen balance.

Maintenance of a high-protein diet stimulates adaptive responses that augment lipid utilization and consistently enhances endurance exercise performance.

At the same relative workload after training, women display an exaggerated shift toward lipid catabolism, whereas men do not.

A lipid can be of plant or animal origin.

__________ is the preferred fuel during intense aerobic exercise because it rapidly supplies ATP via oxidative processes.

Exercise performances of long duration require a fairly steady energy supply derived aerobically without reliance on lactate formation.

Carbohydrate and lipid breakdown use identical pathways for acetyl-CoA oxidation.

Macronutrient energy sources for ATP resynthesis during exercise include all of the following except __________.

Lactate in the body:

__________ and lipid contribute energy equally during moderate-intensity exercise.
