Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.
Inosine the unusual nucleoside which is found in tRNA but not in mRNA.
Inosine is derived from the nucleoside adenosine, adenosine is present in mRNA, however in case of tRNA, there is deamination of adenosine and thus, inosine is formed.
The enzyme that is responsible for carrying out this reaction is called as tRNA A:34 deaminases, here the position 34 indicates that the deamination takes place at position 34 of the tRNA.
The formation of inosine is essential for the wobble base pairing to take place.
The formation of inosine takes place when the hypoxanthine attaches to a ribose ring with the help of the beta glycosidic bond.
This can only be due to the fact that the Universe is expanding. Further, by measuring the distance to the galaxies, one finds that the velocity of recession is proportional to the distance of the galaxy from us. This is called Hubble law after Edwin Hubble who was the first to discover it.
