Adenosine diphosphate (ADP) is formed by the removal of one phosphate from an ATP molecule by enzymes called ATPases.
Adenosine diphosphate (ADP) is an organic molecule involved in the central part of the metabolism of the cell that generates energy.
The interconversion of ATP and ADP takes place in various aspects of cellular metabolism.
Another process in which ATP and ADP act together to supply energy is in the fast twitch of muscle cells.
In mammals, ADP is involved in blood platelet activation, and is stored within platelets.
A derivative of ADP is adenosine diphosphate ribose, in which the sugar ribose is linked to the final phosphate of ADP by an ester linkage.
Explanation:
In the given question, the digestion of monosaccharides has been discussed and the steps of digestion in the digestive system are:
1. The digestion of carbohydrates begins in the mouth where amylase breaks down the starch.
2. The sugars are not completely digested in the mouth therefore they travel from mouth to the stomach.
3. In the stomach, there are no enzymes to digest the sugars.
4. Then, food enters the intestine where intestinal secretions breakdown the sugars.
5. The intestinal juice breaks down the oligosaccharides into diassacharides and these disaccharides are further broken down by maltase, sucrase and lactase.
6. After this, the monosaccharides are formed and these are easily absorbed into the bloodstream.
7. Pancreatic amylase breaks down starch into monosaccharides.
This completes the digestion of the carbohydrates.
