In impaired glucose tolerance (IGT), the levels of blood glucose are between normal and diabetic. People with IGT do not have diabetes. Each year, only 1-5% of people whose test results show IGT actually develop diabetes. And with retesting, as many as half of the people with IGT have normal oral glucose tolerance test results. Weight loss and exercise may help people with IGT return their glucose levels to normal. With diet and exercise as many as 60% will not developed diabetes or it will be considerably slowed in its development.
Reaction rates, temperature and catalysis. 1  As learned in previous modules, the rate of a reaction is increased by using a catalyst or increasing the temperature. 2  The effect of using a catalyst and increasing the temperature can be explained using the collision theory. The collision theory of reactions. The basic principle of the collision theory is that chemicals react when their particles collide with a certain minimum energy.
Best Answer: As you increase the temperature the rate of reaction increases. As a rough approximation, for many reactions happening at around room temperature, the rate of reaction doubles for every 10Â°C rise in temperature.The more finely divided the solid is, the faster the reaction happens. catalyst is to help to increase the rate of chemical reaction by changing the energy pathway to a lower activation energy pathway. That is increasing the frequency of collisions between reactants. The higher the collision per unit the higher the rate of reaction.
