What is respiration?

If you have being looking for a website where you can get all the biology questions and answers then look no further because we are here to help you.

A respiration: is the process by which living things breakdown of food nutrients/organic substances to release energy for metabolic activities of the body, with or without the use of oxygen.

There are two types of cellular respiration Aerobic and Anaerobic respiration

What is Aerobic respiration?

Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, it produces carbon dioxide, water and energy.

What is Anaerobic respiration?

Anaerobic respiration is the term by which glucose breaks down without oxygen. The Chemical reaction transfers energy from glucose to cell. It produces lactic acid, rather than carbon dioxide and water.

Let’s look at the difference between Aerobic respiration and Anaerobic respiration.

(1) Aerobic respiration takes place in the presence of oxygen; whereas Anaerobic respiration takes place in the absence of oxygen.

(2) Aerobic respiration releases more energy than Anaerobic respiration.

(3) Carbon dioxide and water are the end products of Aerobic respiration while alcohol is the end product of Anaerobic respiration.

Now let’s take a look at the similarities between Aerobic respiration and Anaerobic respiration.

(1) Food is oxidized in both cases and energy is released.

(2) They both use glucose as the starting point. This is called the substrate.

(3) Both aerobic respiration and anaerobic respiration produces ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration.

The two types of respiration in humans are:

(1) External Respiration:
(2) Internal Respiration

(A) External Respiration, that involves the inhalation and exhalation of gases

(B) Internal Respiration, that involves the exchange of gases between blood and body cells.
