ATP Production

What happens during rest conditions when the body creates energy (ATP)?

• The body has insufficient oxygen to function at a resting level.

• The body has sufficient oxygen to continue functioning at a resting level.

• The body requires anaerobic activity to produce energy.

• The body relies on increased oxygen intake after rest.

What happens during active conditions when the body creates energy (ATP)?

• Physical exertion causes insufficient oxygen availability, requiring increased oxygen intake during or after effort.

• The body has an excess of oxygen to function at high levels.

• Active conditions occur only during rest.

• Energy is created solely through aerobic activity.

What characterises energy production in the body when it is at rest?

• Energy demand is high because the body is preparing for activity.

• The body is under physical stress, with elevated breathing and heart rates.

• Energy is produced aerobically due to an abundant oxygen supply, with low and stable breathing and heart rates.

• The body produces energy anaerobically to maintain resting functions.

Approximately ______ of the ATP in this state comes from the breakdown of ______, and ______ comes from the breakdown of glucose and glycogen stores in both muscle and liver.

The production of ATP from both sources occurs in the ​ (a)   , the bean shaped ​ (b)   located in the muscle cell. The mitochondria is the centre for ​ (c)   energy metabolism.

• mitochondria
• “powerhouse”
• cytoplasm
• aerobic
• anaerobic

What does the statement "This covers any physical state more exertive than rest" refer to?

• Resting metabolic rate

• Physical activity that requires more exertion than rest

• Sleeping conditions

• Energy production only during anaerobic exercise

The ATP produced for each are determined by several factors:

The length of time​ (a)   of the exercise

How hard you are working​ (b)   in the exercise

How well developed your cardiorespiratory system is ​ (c)  

The degree of ​ (d)   in between successive bouts of exercise

• (duration)
• (intensity)
• (aerobic fitness)
• recovery

Why would the body prefer to produce energy aerobically?

• It requires less oxygen to function.

• It is the most efficient system and produces no fatiguing by-products like lactic acid.

• It generates energy more quickly than any other system.

• It relies solely on glucose for energy production.

Why does the body need to use anaerobic systems during physical activity?

• Anaerobic systems are more efficient than aerobic systems.

• It takes time to deliver the necessary oxygen to the lungs, blood, and working muscles, so the body relies on anaerobic systems that do not require oxygen.

• Anaerobic systems are the only way to produce energy during exercise.

• The body cannot absorb oxygen during exercise.

Which energy system involves the breakdown of phosphocreatine without oxygen?

• The Aerobic System

• The Lactic Acid System

• The ATP-PC System

• The Glycolytic System
