Respiration is a normal breathing process in human beings, plants and animals. In cellular respiration the cells release energy in glucose and the energy that is released from the cells is used to produce Adenosine-5 – triphosphate, thus whatever energy is needed by the cells is supplied by ATP. Adenosine-5-triphospate (ATP) plays an important role and performs many functions in a cell.
- It stores energy and gives energy to cells for performing other activities.
- It helps in regulating biochemical pathways
The process through which ATP is produced is called aerobic cellular respiration
What is Aerobic Cellular Respiration?
It is the process by which the energy is released from glucose in the presence of oxygen and this process is called aerobic cellular respiration. This respiration takes places only in the presence of oxygen. A simple formula would help to understand this better.
Glucose + Oxygen = Carbon dioxide + Water + Energy (ATP)
There are three different stages in Aerobic Cellular Respiration
Glycolysis: Glycolysis takes place in the cytosol of the cell. In this a part of the glucose is oxidized and is broken into 3 molecule of carbon and therefore in this process energy is produced- 2 ATP molecules and 2 Nicotinamide Adenine Dinucleotide molecules are there and each NADH carries 2 energy electrons and later the cell uses the electrons.
Krebs Cycle: In the second stage of aerobic cellular respiration the pyruvate molecules release the energy which is stored between molecules and this energy is released in the form of ATP. This process goes in a cycle and is called cytric acid cycle.
Electron Transport Chain: This is the third stage of aerobic cellular respiration. In the glycolysis and krebs cycle the entire energy does not released from the glucose. In this the remaining energy is released from the glucose by the electrons. Electron transport chain happens when electrons carry proteins to the inner membrane of the cell and the electrons with the protons adds to the oxygen. When protons move along the cell membrane ATP is produced. This process is known as chemiosis.
