Exercise Metabolism

How is glucose stored in the body?

• As triglycerides in adipose tissue

• As glycogen in muscle and liver

• As free glucose in the bloodstream

• As amino acids in muscle tissue

What is the primary energy system used at the onset of exercise?

• Aerobic glycolysis

• Anaerobic glycolysis

• Phosphocreatine (PCr) system

• Beta-oxidation of fats

Which energy pathway becomes important after several seconds of exercise?

• Aerobic glycolysis

• Anaerobic glycolysis

• Phosphocreatine (PCr) system

• Beta-oxidation of fats

What is the role of adipose tissue in energy storage?

• Stores glucose as glycogen

• Stores fat as triglycerides

• Stores protein as amino acids

• Stores ATP directly

What does "oxygen deficit" refer to in the context of exercise?

• The immediate increase in oxygen consumption at the start of exercise

• The lag in oxygen consumption at the start of exercise

• The decrease in oxygen demand during exercise

• The surplus of oxygen available during exercise

Which pathways does the body rely on during the initial period of oxygen deficit?

• Aerobic pathways

• Anaerobic pathways

• Photosynthetic pathways

• Glycolytic pathways

What is a byproduct of anaerobic glycolysis that can contribute to fatigue?

• Oxygen

• Glucose

• Lactate

• ATP

What does EPOC stand for?

• Excess Post-exercise Oxygen Consumption

• Elevated Physiological Oxygen Consumption

• Enhanced Performance Oxygen Capacity

• Extra Post-exercise Oxygen Conversion

Why does EPOC occur?

• To decrease oxygen levels after exercise

• To restore the body to its pre-exercise state

• To increase lactate production

• To reduce ATP synthesis

What happens to phosphocreatine stores during exercise?

• They increase rapidly

• They remain constant

• They are depleted quickly

• They convert to glucose
