Q

What are the differences between aerobic and anaerobic respiration?

A

Aerobic respiration occurs with oxygen and releases more energy but more slowly. Anaerobic respiration occurs without oxygen and releases less energy but more quickly

Q

Why do complex multicellular organisms require specialised breathing systems and what are they?

A

because the body contains so many different types of cells and organs that work together and need oxygen to keep the body stable like diffusion.

Q

What makes diffusion rate high?

A
  1. Large surface area
  2. Steep concentration
  3. Thin alveoli’s and capillary walls so distance is short.
  4. Flat alveoli and capillary walls.
  5. Moistened air so oxygen dissolves quicker.

Q

What are the effects of excersize on breathing?

A
  • breathing rate increases
  • exersize inhilation Is deeper i.e volume increases
  • excersize cells are respiring more using up more oxygen and producing more co2.

Q

is there a difference between respiration and breathing?

A

yes there is. respiration is a process that requires oxyygen to release energy. breathing is ventilation.

Q

with reference to cellular respiration, why does breathing rate change before and after exercise?

A

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. also exercise increases the rate of cellular respiration.
