Chemical Form Mercury Chemical Form Mercury May Travel Fish
699 wordsIntroduction Mercury is a silvery, liquid metal at room temperature. It is sometimes referred to as one of the "heavy metals. " Like water, mercury can evaporate and become airborne. Because it is an element, mercury does not break down into less toxic substances. Once mercury escapes to the environment, it circulates in and out of the atmosphere until it ends up in the bottoms of lakes and oceans. Depending on its chemical form, mercury may travel long distances before it falls to earth with pr...

N P Active Site
952 wordsGlycolysis Reaction 1 Glucose -> Glucose 6 -phosphate (G- 6 -P) The first stage of glycolysis starts from reaction of phosphorylation. Phosphorylation is catalyzed by hexokinase. It is an endothermic ATP dependent reaction and requires energy from ATP. ATP is hydrolyzed to ADP and phosphate. In such a way, glucose receives phosphate and energy. To sum up, the reaction is as follows: glucose + ATP a glucose- 6 -phosphate + ADP Reaction 2: Glucose 6 -phosphate (G- 6 -P) -> F- 6 -P (Fructose 6 -pho...
