Q

How can the rate of oxygen consumption be used as an estimate of metabolic rate?

A

When respiration rate increases both oxygen consumption and carbon dioxide production increases
Aerobic respiration requires oxygen

Q

Why do breathing and pulse rates increase during exercise?

A

When you do vigorous exercise your body needs to supply more oxygen to your muscles for aerobic respiration

Q

How is lactic acid removed during recovery?

A
  • hard exercise causing lack of oxygen in cells
  • the incomplete breakdown of glucose
  • continued panting replacing oxygen allowing aerobic respiration
  • increased heart rate ensuring that blood carries lactic acid away to the liver

Q

What is respiration?

A

Respiration is a chemical reaction that takes place in the mitochondria. It is when glucose reacts with oxygen to produce carbon dioxide and energy is released
