The products of the digestive system are actually tied directly to the circulatory system in that the organs of the digestive system are used to turn ingested food into products that can be absorbed by the blood and then carried to other organs for use as energy or other functions.There are also several links between the digestive system and the respiratory system in that there are organs and muscles that serve both, for example the diaphragm which works to force air into and out of the lungs as well as to force waste products out of the digestive system.<span>All of the systems have to work together as well, without the intake of oxygen and exhalation of carbon dioxide, the function of the digestive system would grind to a halt.  Without the production of glycogen and other things necessary for muscular function, produced by the digestive system and then distributed by the circulatory system, all three functions would cease.</span>

Explanation:
protein is the element responsible for building up of cells and the nucleic acid is embedded in the cell, so protein builds the whole cell including the nucleic acids.. the nucleic acid is also packed by histones which is a proteinous structure. both are important because, in the cell all organelles require protein for their growth and likewise the encoding of the genetic information carrier
 
        
             
        
        
        
The answer to the question mentioned above is the "Chloroplast".
 
During the light-dependent reaction of photosynthesis, chloroplast is decomposed to supply hydrogen ions tp produce NADPH, and important energy-carrying molecule used to help produce glucose during the light dependent reaction.
