Biology Respiration

Question 1

Explain the effects of exercise on respiration

Answer 1

Exercise increases the rate of respiration, as more energy is demanded by muscles to contract during exercise, therefore more oxygen is needed to be brought to them.

Question 2

Describe the effects of exercise on respiration

Answer 2

Increased rate of respiration depending on intensity of exercise

Question 3

What is anaerobic respiration

Answer 3

Respiration where oxygen is no longer enough to react and form glucose, so instead energy is made without, but causing lactic acid build up

Question 4

Compare aerobic to anaerobic respiration

Answer 4

Aerobic is respiration involving oxygen

Anaerobic is without oxygen.

Question 5

Compare anaerobic respiration in animals, bacteria and yeast

Answer 5

Some micro organisms produce lactic acid during anaerobic respiration, the becteria used to form yoghurts, for example. Other micro organisms like yeast form ethanol and carbon dioxide, in yeast cells, this is referred to as fermentation.
