Lecture 15 Content Knowledge Questions

Front

What is the primary energy system used during prolonged, low-intensity activities?

Back

Aerobic energy system.

Front

Which energy system produces the most ATP per molecule of substrate?

Back

Oxidative system.

Front

What energy system is primarily used for high-intensity activities lasting less than 10 seconds?

Back

ATP-PCr system.

Front

What does beta oxidation involve the breakdown of?

Back

Fatty acids.

Front

Which energy system is predominant during a 2-minute run?

Back

Anaerobic Glycolysis system.

Front

Define the ATP-PCr system.

Back

A short-term energy system that provides immediate energy through the breakdown of phosphocreatine.

Front

What is anaerobic glycolysis?

Back

A metabolic pathway that converts glucose into energy without the use of oxygen, producing lactic acid as a byproduct.

Front

Explain the role of the oxidative system in energy production.

Back

The oxidative system uses oxygen to convert carbohydrates, fats, and proteins into ATP, primarily during prolonged, moderate-intensity activities.

Front

What is the main substrate for the oxidative energy system?

Back

Carbohydrates and fats.

Front

How does the body utilize fatty acids during exercise?

Back

Fatty acids are broken down through beta oxidation to produce ATP in the oxidative system.
