Differentiate between aerobic and anaerobic respiration.​

Answer 1

$\Huge{\boxed{\sf{\underline{\underline{Answer}}}}}$

_________________________________________________

What is Respiration ?

• It is the process of taking in oxygen and releasing out carbon dioxide.

• It is the act of respiring; Inhalation and Exhalation of air (breathing) .

• The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.  

Respiration is basically classified into 2 types namely :

i) Aerobic and

ii) Anaerobic

DIFFERENTIATION BETWEEN AEROBIC AND ANAEROBIC RESPIRATION.

Aerobic Respiration :-

• Takes place in presence of oxygen.

• End products - Carbon dioxide and water.

• More energy is released. ( 38 ATP )

• Takes place in cytoplasm and mitochondria.

• Complete oxidation of glucose takes place.

Anaerobic Respiration :-

• Take place in absence of oxygen.

• End products - ethanol and carbon dioxide.

• Less energy is released. ( 2ATP )

• Take place in only in cytoplasm.

• Incomplete oxidation of glucose takes place.

$\huge\bold\green{Question}$

Differentiate between aerobic and anaerobic respiration.

$\huge\bold\green{Answer}$

The primary organs of the respiratory system are lungs. They carry out the exchange of gases as the breathing process occurs. The chief organ of the respiratory system is the lung, which carry out this exchange of gases as we breathe. When we breathe in or inhale, the ribs expand and the diaphragm flattens which increases the size of the chest cavity and the air is filled into the lungs. The blood brings carbon dioxide from the rest of the body and the oxygen is taken up by blood and carried to all the cells of the body.

•°• The main function are :-

→ Distribution of air and carry out gas exchange.

→ It filters and humdifies the air that we breathe in.

→ The organs of this system also take part in speech and smell.

→ Maintains balance in the internal elements of the body.

→ Carries out internal as well as external respiration.

$\bold\orange{Aerobic\:Respiration}$

Aerobic respiration is a process of respiration when oxygen is involved and releases energy for the cells from glucose that is sugar. Aerobic Respiration breaks down molecules of sugar ( glucose ) in order to form ATP ( Adenosine Triphosphate)

•°• The main function are :-

→ It is a permanent process that continuous throughout the life of plants and animals

→ Energy is released in greater amounts in the form of ATP to 36 ATP molecules

→ The process is non toxic to both plants and animals

→ End products are CO2 and H2O

•°• Aerobic respiration is basically occurred in :-

Humans ,animals , some insects, birds etc.

•°• Reaction of aerobic respiration :-

Glucose + oxygen → carbon dioxide + water

$\bold\orange{Anaerobic\:Respiration}$

Oxidation of food material in the absence of oxygen is known as anaerobic reaction. It occurs in yeasts and also in humans when there is lack of supply of adequate amount of oxygen.

•°• The main function are :-

→ The process occurs in the absence of oxygen .

→ It is a permanent process in anaerobic microorganisms but a temporary process in higher plants and animals only under anaerobic condition .

→ Energy is released in lesser amounts in the form of ATP - (2 ATP )molecules. Heat is also generated in fermentation .

→ The process often toxic to both plants and animals .

→ End products are ethanol and CO2

•°• Reaction of anaerobic respiration :-

C6H12O6 → 2C2H5OH + 2CO2 + 21kcal
