Types of Respiration

Three type of Respiration according to location

External Respiration: occurs in the lungs where Exchange of Oxygen and Carbon Dioxide take place between  Environment and Blood.

Internal Respiration: occurs in the tissues where Oxygen and Carbon Dioxide Exchange between  Blood and Tissue.

Cellular Respiration: It is Utilization  of Oxygen within the Cells and Excretion of Carbon Dioxide by the Cell.

Two type of Respiration according to oxygen use

Anaerobic Respiration: occurs in the tissues when availability of oxygen is too low to undergo the process of aerobic Respiration. Respiratory substrate(Glucose) partially oxidised. The products of anaerobic respiration is ethyl alcohol/lactic acid, Carbon dioxide and 2 ATPs.   There are two main types of anaerobic respiration:

• Alcoholic fermentation 
• lactic acid fermentation

In Alcoholic fermentation 2 Ethanol + 2 Co2 is produce,

In lactic acid fermentation  2 lactic Acid produce.

Aerobic Respiration: Aerobic Respiration requires oxygen in order to Generate ATP. Completely oxidised of Respiratory substrate(Glucose) leads to production of Carbon dioxide, water and 37 ATPs.

There are two stages of aerobic Respiration

• Glycolysis
• TCA cycle
