Question

) Differentiate between aerobic and anaerobic respiration? Write the

chemical equation for them.


(b) How do the cockroaches breathe?​

Answer 1

Answer:

In the presence, of oxygen the breakdown of gulcose with the release carbon dioxide, water

energy

Answer 2

Answer:

Aerobic Respiration

1 Oxygen is present when this form of respiration takes place

2 Gases are exchanged in this form of respiration.

3 It can be found in the cytoplasm and the mitochondria.

4 Glucose breaks down into carbon dioxide and water.

5 All higher organisms such as mammals have this type of respiration.

6 Glucose + Oxygen → Carbon dioxide + Water + Energy

Anaerobic Respiration

1 Oxygen is absent when this form of respiration takes place.

2 Gases are not exchanged in this form of respiration.

3 It can be found only in the cytoplasm.

4 Glucose breaks down into ethyl alcohol, carbon dioxide and energy.

5 Lower organisms such as bacteria and yeast use this type. In other organisms, it occurs during heavy activities.

6 Glucose → Alcohol + Carbon dioxide + Energy

2 They do this by using a very efficient breathing system that uses air filled tubes, called trachea, to deliver oxygen directly to cells. Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing
