IB SEHS Topic 3: Energy Systems

Front

What is glycogen?

Back

Glycogen is a polysaccharide that serves as a form of energy storage in animals, primarily found in the liver and skeletal muscles.

Front

Where is glycogen primarily stored in the human body?

Back

Glycogen is primarily stored in the liver and skeletal muscle.

Front

What is the process of breaking down glycogen into glucose called?

Back

The process of breaking down glycogen into glucose is called glycogenolysis.

Front

What is the role of creatine phosphate in energy systems?

Back

Creatine phosphate provides a rapid source of energy for ATP resynthesis during short bursts of high-intensity activity.

Front

What are the main features of the ATP-CP energy system?

Back

The ATP-CP system provides immediate energy for short-duration, high-intensity activities, primarily using creatine phosphate to regenerate ATP.

Front

What is the difference between anaerobic and aerobic glycolysis?

Back

Anaerobic glycolysis occurs without oxygen and produces lactic acid, while aerobic glycolysis occurs with oxygen and produces more ATP.

Front

What characterizes saturated fats?

Back

Saturated fats have no double bonds between the individual carbon atoms of the fatty acid, making them solid at room temperature.

Front

What is the primary by-product of anaerobic glycolysis?

Back

The primary by-product of anaerobic glycolysis is lactic acid.

Front

How does the body utilize ATP during exercise?

Back

ATP is used as the primary energy currency in the body, providing energy for muscle contractions and other cellular processes.

Front

What is the significance of the Krebs cycle in energy production?

Back

The Krebs cycle is a key metabolic pathway that generates ATP through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.
