Question

what is respiration ? how many types of respiration​

Answer 1

Answer:

Respiration: The process of releasing energy by the oxidation of food is known as respiration. Respiration is of two types aerobic and anaerobic.

Aerobic respiration:

i. Respiration which takes place in the presence of oxygen is known as aerobic respiration.

ii. During this process, food (glucose) is broken down into carbon dioxide and water in the presence of oxygen.

iii. Energy release in this process is stored in the form of adenosine triphosphate (ATP).

Anaerobic respiration:

i. Respiration which takes place in the absence of oxygen is known as anaerobic respiration.

ii. In anaerobic respiration in microorganisms, glucose is broken down into ethanol and carbon dioxide with the release of energy. Lactic acid is the end-product of respiration in muscle cells, while CO$$_2$$CO2 and ethanol are formed in plants.

Answer 2

Answer:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

There are two types of Respiration:

• Aerobic respiration ( in the presence of Oxygen)
• Anaerobic Respiration( in the absence of Oxygen)
