Aerobic Respiration
Aerobic respiration is the expulsion of energy in the presence of energy. It occurs when the energy from organic substrate or glucose is released in the presence of oxygen. Oxygen in the air is very essential for aerobic respiration. The word aerobic means in air and is is related with air. The oxygen present in the air is utilized for aerobic respiration. Anaerobic respiration is the opposite of aerobic respiration and it occurs in the non-presence absence of oxygen.
Glucose molecular has a molecular model. A glucose molecular contains 6 atoms of carbon, 6 atoms of oxygen and 12 atoms of Hydrogen.
The energy is released when the tissues break down the glucose. This energy is used for making a substance known as ATP – Adenosine Tri Phosphate. This energy is utilized for processes like muscle contractions in the body.
Aerobic Respiration in Living Things
Aerobic respiration is helpful in releasing carbon dioxide and it occurs in all living things. The excess water and toxic substances are also secreted from the body through aerobic respiration. Glucose is the main source of energy.
A few organisms in the atmosphere can breathe even if there is no oxygen and air. This is known as anaerobic respiration. In this process, the amount of energy released is very less and the toxic substances are accumulated in the body. It produces lactic acid acid in the muscles leading to muscle cramps.
Anaerobic respiration makes the bacteria in milk to produce sour lactic acid. It turns toxic and the yeast produces toxic alcohol. The toxicity level increases and the yeast cannot survive in this situation.
Stages of Aerobic Respiration
There are three stages of aerobic respiration. They are:
First Stage: The first stage is known as glycolysis. Waste products of carbon dioxide are produced in this stage.
Second Stage: In second stage, the chemical reactions happen in a complex manner.
Third Stage: Third stage is called electron transport phosphotylation which produce problematic ATP
The primary byproducts of aerobic respiration is divided into two. They are water and carbon dioxide.
