Reaction Rates Factors affecting the rate of chemical rxns S

Reaction Rates Factors affecting the rate of chemical rxns: Substrate and Product Concentrations -High concentrations of substrates will generating will generally increase the rate of the rxn, whereas high concentrations of products will slow the rxs. This is known as the \"Mass Action Effect\". Accumulation of product may slow the rate of the reaction and influence Delta G. ATP rightarrow ADP + P - OH + H^+ + 7.3 k cals During intense exercise, ATP is converted to ADP and H^+ is released, P-OH can also accumulate. How does this reaction and the mass action effect, effect exercise performance and fatigue?

Solution

ATP breakdown into ADP, inorganic phosphate molecule and hydrogen ion also causes release of energy which results in biological work and would be helpful while doing exercise.

The law of mass action states that the direction of the reaction in a solution is driven by the concentration of reactants or products. In the aforementioned reaction, the hydrolysis of ATP results in the increase in ADP as well as Pi which increases the rate of creatine kinase and adenylate kinase reactions to fill up the ATP supply.
