ATP is known as the energy currency of the cell justify
Answers
Answer:
Explanation:
ATP is known as adenosine triphosphate, and it is a molecule containing carbon, hydrogen, nitrogen, oxygen and phosphorus. ATP is the energy currency of the cell because, it is the most preferred energy molecule in the cell. Its preference is due to the following factors:
1. It donates its phosphoryl groups to release energy.
2. On hydrolysis, it releases a high negative Gibbs free energy which can be used to drive many important biosynthetic reactions in metabolic pathways.
3. The presence of adenine and ribosyl groups provide additional features for attachment to enzymes so it is able to regulate enzymatic activities
Answer :
ATP functions as the energy currency for cells. It allows the cell to store energy briefly and transport it within the cell to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphates attached. As ATP is used for energy, a phosphate group or two are detached, and either ADP or AMP is produced. Energy derived from glucose catabolism is used to convert ADP into ATP. When ATP is used in a reaction, the third phosphate is temporarily attached to a substrate in a process called phosphorylation. The two processes of ATP regeneration that are used in conjunction with glucose catabolism are substrate-level phosphorylation and oxidative phosphorylation through the process of chemiosmosis.
