Trophic level: the feeding level of an organism in a food web or chain. Food web: a diagram showing a series of interconnected food chains and the flow of energy through an ecosystem. Food chain: a diagram showing the flow of energy from one trophic level to the next. E.g. Consumer or decomposed Consumer: an organism which feeds on other organisms to obtain its nutritional requirements (part of a food web/chain). Producer: an organism capable of trapping the suns energy and converting it to sugar in the process of photosynthesis. Therefore the term food web is the term used to include all of the above. 
hope this helps, :)
        
                    
             
        
        
        
Following the treatment, the Fetal Stem Cells will travel throughout the body, detecting damaged cells and tissue and attempts to restore them. The Fetal Stem Cells can also stimulate existing normal cells and tissues to operate at a higher level of function, boosting the body’s own repair mechanisms to aid in the healing process. These highly adaptive cells then remain in the body, continually locating and repairing any damage they encounter.

The fructose 1-phosphate pathway can deplete intracellular phosphate/ ATP. 
Explanation:
Fructose 1-phosphate is a derivative of fructose. For understanding in better way fructose metabolism has three enzymes. Fructose- bisphosphate aldolase B, fructokinase and Adenosine triphosphate. These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase. 
After it is converted into trioses dihydroxyacetone phosphate as well as glyceraldehyde through aldolase.  With glucose metabolism Fructose get synergistic effect
