Aerobic and Anaerobic Respiration

Question 1

Characteristics of aerobic respiration

Answer 1

• Long in duration
• Low to medium intensity
• Most efficient way of producing energy
• Muscles supplied with oxygen

Question 2

Characteristics of anaerobic respiration

Answer 2

• Short in duration
• High intensity
• Maximum effort
• Muscles not supplied with oxygen
• Can only provide muscles with energy for short periods of time

Question 3

Equation for anaerobic respiration

Answer 3

Glucose + oxygen = carbon dioxide + water + energy

Question 4

Equation for anaerobic respiration

Answer 4

Glucose = lactic acid + energy

Question 5

Fats as an energy source

Answer 5

• Energy source for aerobic respiration
• Require oxygen to break down into glucose
• Slow to break down
• Once broken down give large quantities of energy for longer

Question 6

Carbohydrates as energy sources

Answer 6

• Energy source for aerobic and anaerobic
• Do not require oxygen to break down into glucose
• Do not give as much energy as fats
• Quicker to break down and release more energy than fats initially
