Exam 3: Energy Systems and Exercise

The duration of the creatine phosphate energy system is approximately __________ to __________ second(s).

Blood glucose

Which of the following statements regarding energy systems is false?

The energy system that has the slowest rate of ATP replenishment is oxidative phosphorylation.

If creatine phosphate is nearly depleted in skeletal muscle by high-intensity exercise, approximately how long does it take to restore creatine phosphate levels?

Anaerobic glycolysis

Long distance running would depend primarily on the creatine phosphate system as a source of ATP.

Fatigue in the oxidative phosphorylation energy system via the use of carbohydrate is associated with ___________.

Which of the following statements regarding ATP is true?

Match the term with its definition. a.Insulin b.Oxidized c.VO₂ max d.Palmitate e.Reduced f.Alanine g.Glycogenolysis h.Lactate i.Lipolysis j.RER -ratio of carbon dioxide production to oxygen consumption

It is biochemically impossible to convert carbohydrate to fatty acids.

Discuss the concept of the respiratory exchange ratio (RER) and how the proportions of fat and carbohydrate oxidation change as exercise intensity and/or duration changes.

As exercise intensity increases, the percentage of energy from fat metabolism decreases.

Highly aerobic muscle fibers and other tissues can use lactate as an energy source.

Anaerobic glycolysis

If creatine phosphate is nearly depleted in skeletal muscle by high-intensity exercise, how is it rephosphorylated?

Creatine phosphate

The elevated oxygen consumption during recovery from an exercise bout is called EPOC or ____.

The fastest and least complex energy system used to produce ATP is ____.

Explain why anaerobic energy systems are not entirely anaerobic. Answer Key
