Aerobic Energy System

What are the characteristics of the aerobic energy system?

• Uses oxygen to produce energy

• Functions without oxygen

• Only active during sleep

• Produces energy quickly

What aerobic energy system has the slowest rate of ATP production?

• Aerobic glycolysis

• Aerobic lipolysis

• Anaerobic glycolysis

• Anaerobic lipolysis

What characterizes the aerobic glycolysis system?

• Unlimited capacity and slowest ATP rate

• Limited capacity and moderate ATP rate

• Unlimited capacity and fastest ATP rate

• Limited capacity and slowest ATP rate

Which of the following best describes the capacity and power of the aerobic lipolysis system?

• Least powerful, unlimited capacity

• Most powerful, limited capacity

• Moderate power, moderate capacity

• Least powerful, limited capacity

What is the end product of anaerobic glycolysis in the breakdown of glucose?

• CO2 + H2O + heat + ATP

• Lactic Acid + H+

• ATP only

• Pyruvic Acid

During aerobic glycolysis, what is the final output when glucose is completely broken down?

• Lactic Acid + H+

• ATP only

• CO2 + H2O + heat + ATP

• Pyruvic Acid

What is the primary difference in the byproducts of glucose breakdown between anaerobic and aerobic glycolysis?

• Anaerobic produces more ATP than aerobic.

• Anaerobic results in lactic acid, while aerobic results in CO2, H2O, and heat.

• Aerobic produces pyruvic acid, while anaerobic does not.

• Anaerobic uses oxygen, while aerobic does not.

What is the preferred fuel source for the aerobic system during glycolysis?

• Proteins

• Carbohydrates

• Nucleic acids

• Minerals

Which type of muscle fibers does the aerobic system predominantly recruit?

• Fast-twitch

• Intermediate-twitch

• Slow-twitch

• No specific type

For how long must an activity last for the aerobic system to be dominant?

• More than 30 seconds

• More than 75 seconds

• More than 2 minutes

• More than 5 minutes
