Facts about Cellular Respiration.

Cellular Respiration is known as a complex process in which energy in the form of ATP is released from food molecules ingested by organisms. Autotrophs such as green plants produce their own food through the process of photosynthesis. On the other hand, heterotrophs such as humans feed on plants or other heterotroph. In all kinds of food substances, chemical energy is stored. This stored energy is then converted into another form of energy-carrying molecule which is known as ATP or Adenosine Triphosphate. There are also other simpler substances produced which are CO2 and H2O. This process is collectively known as cellular respiration.

We have two main types of cellular respiration. Moreover, both start with glycolysis, a process by which one glucose molecule is broken down into two pyruvic acid molecules. One type of cellular respiration is anaerobic respiration. In this process, pyruvic acid is broken down without the use of oxygen. The by product of this process varies but usually, lactic acid in animal cella sn some unicellular organims and ethyl alcohol in some plant cells and some unicellular organisms such as yeast.

Another type of respiration involves the use of O2. It is termed as aerobic respiration. In this process, oxygen is utilized in order to produce ATP which is the source of cellular energy.
