Is hydrolysis a mechanical or chemical?
- Hydrolysis is a common form of a chemical reaction where water is mostly used to break down the chemical bonds that exists between a particular substance. Hydrolysis is derived from a Greek word hydro meaning water and lysis which translates to the word break or to unbind.
Why is this reaction considered exothermic?
- In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants. In the presence of water, a strong acid will dissociate quickly and release heat, so it is an exothermic reaction.
Does hydrolysis involve an increase in entropy?
- Why does ATP Hydrolysis increase entropy? Today in AP Bio we learned that ATP Hydrolysis is spontaneous because entropy increases and it is exothermic. However, the number of molecules on the products side isn't greater than the reactanta side (water + atp -> adp + phosphate).
