- In all green plants, cellular respiration takes place in the mitochondria of the cell in the presence of oxygen.
- C6H12O6 (Glucose) + 6O2 (Oxygen) → 6CO2 (Carbon dioxide) + 6H2O (Water) + ATP (Energy)
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the surrounding environment.

It is a type of cellular respiration that takes place in the presence of oxygen and produces energy. It is observed in both plants and animals and the end product of this type of respiration is water and Carbon dioxide (CO2). Have a look at the reaction which takes place during aerobic respiration. Glucose (C6H12O6) + Oxygen 6(O2) → Carbon-dioxide ...
In plants, aerobic respiration starts when oxygen or O2enters plant cells through the stomata found in the epidermis of leaves. Then the process of photosynthesis is carried out which produces food for the plant body and releases energy. The chemical reaction that takes place is below: Carbon dioxide 6(CO2) + Water 6(H2O) → Glucose (C6H12O6) + Oxyg...
is another type of cellular respiration that takes place in the absence of oxygen and produces energy. In this process, glucose breaks down without the help of oxygen and the by-products produced are alcohol, (CO2) and energy or ATP. The process takes place in the cytoplasm of a cell. The chemical reaction of this process is as follows: Glucose (C6...
External respiration or breathing is one of the methods for obtaining oxygen from the environment. In animal organisms, the process of external respiration is performed in several different ways. Animals that lack specialized organs for respiration rely on diffusion across external tissue surfaces to obtain oxygen whereas others either have organs ...
Internal respiratory processes explain how oxygen gets to body cells. Internal respiration involves the transportation of gases between the blood and body tissues. Oxygen within the lungs diffuses across the thin epithelium of lung alveoli (air sacs) into surrounding capillaries containing oxygen-depleted blood. At the same time, carbon dioxide dif...
The oxygen obtained from internal respiration is used by cells in cellular respiration. To access the energy stored in the foods we eat, biological molecules composing foods (carbohydrates, proteins, etc,) must be broken down into forms that the body can utilize. This is accomplished through the digestive process where food is broken down and nutri...
(GLUCOSE) C6H12O6+ 2 ADP + 2 PHOSPHATE → 2 LACTIC ACID + 2 ATP During exercise, body muscles use O2to produce ATP faster than they can be supplied. When this happens, muscle cells carry out glycolysis faster than they can provide oxygen to the electron transport chain. This is why lactic acid fermentation takes place in our cells after a long sessi...
Cellular respiration takes place through a range of metabolic pathways. Glucose is broken down into the water, carbon dioxide and some amount of ATP. More ATP is produced later in a process known as oxidative phosphorylation which is powered by the movement of electrons through the electron transport chain. Below is a summary of the different phase...
We all normally obtain energy by aerobic respiration. But when we need extra energy, anaerobic respiration can take place in our muscles for a short time. When we do heavy physical exercise, our muscles need more oxygen. But the supply of oxygen through blood is limited and hence insufficient. During heavy exercise, some of our muscles respire anae...
Respiration is the energy supplying and releasing process in all living organisms by converting food energy into metabolically usable forms of chemical energy. The process releases energy in a controlled step-by-step manner so it could be properly used for all cellular activities such as metabolism and cell division. Various intermediate products o...
