A more social and care centered approach is needed as in these cases relatives and friends play a big role in their over all well being. [...] |
| [...] Temperature; according to the kinetic theory as temperature increases molecules gain more energy resulting in their faster movement. Therefore in context with enzyme activity, the faster the movement of molecules the more often the collisions between the substrate and enzyme will occur over all increasing the rate at which the product is formed. However as before if temperature continues to rise the hydrogen and ionic bonds, which hold the enzyme in shape, will break and lead to the denaturisation of the enzyme. Therefore each enzyme has its optimum working temperature. The concentration of either the enzyme or substrate; by having a higher concentration of substrate molecules there is a higher chance for the enzyme to collide successfully with the substrate and consequently speeding up the rate of the reaction. Increasing the concentration of enzymes may result in the rapid increase of the rate of reaction and the graph may level off very quickly as the reaction takes place as such a high speed. [...] |
