Respiration

Question 1

How is aerobic respiration summarised as ? (Formula)

Answer 1

Glucose + oxygen —-> carbon dioxide + water

Question 2

Does the energy transferred supply all the energy needed for living processes ? True or false

Answer 2

True

Question 3

Describe the effects of exercise on respiration

Answer 3

breathing rate increases so you can get more oxygen to make more energy
Heart rate increases

Question 4

Explain the effects of exercise on respiration

Answer 4

Your heart speeds up to pump extra food and oxygen to the muscles. Breathing speeds up to get more oxygen and to get rid of more carbon dioxide. When a fit person, such as an athlete, exercises the pulse rate, breathing rate and lactic acid levels rise much less than they do in an unfit person

Question 5

What is anaerobic respiration

Answer 5

Anaerobic respiration transfers energy from glucose to cells

Question 6

Compare aerobic to anaerobic respiration

Answer 6

Aerobic respiration, a process that uses oxygen, and anaerobic respiration, a process that doesn’t use oxygen, are two forms of cellular respiration

Question 7

Compare anaerobic respiration in animals, bacteria and yeast

Answer 7

Almost all animals and humans are obligate aerobes that require oxygen for respiration, whereas anaerobic yeast is an example of facilitative anaerobe bacteria
