Question

F. Write true or false and correct the incorrect statement :

1. Aerobic respiration can take place in the absence of oxygen.
2. More energy is released during anaerobic respiration.
3. Respiration is an anabolic process.
4. The end products of aerobic respiration are ethyl alcohol and carbon dioxide.
5. Glucose is completely oxidised during anaerobic respiration.

Answer 1

1 - False

Aerobic respiration can take place in the presence of Oxygen

2 - False

More energy is released during aerobic respiration

3 - False

Respiration is a catabolic process

4 - False

The end products of anaerobic respiration (ethyl alcohol fermentation) are ethyl alcohol and CO2

5 - False

Glucose is completely oxidized during aerobic respiration

Answer 2

1. False

2. False

3. False

4. False

5. False

Step-by-step explanation:

1. Aerobic respiration requires the presence of oxygen

2. Aerobic respiration is 19 times more effective at releasing energy than anaerobic respiration because aerobic processes extract most of the glucose molecules' energy in the form of ATP, while anaerobic processes leave most of the ATP-generating sources in the waste products.

3. Cellular respiration is a catabolic process during which glucose is broken down to release usable energy for a cell.

4. The end products of aerobic respiration are carbon dioxide, water and energy.

5. During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down.
