Question #b9e8e

Answer 1

1. too high the enzyme is destroyed
2. enzymes can not work at the wrong pH
3. 4 The increased concentrations increase the chances of correct collision

Explanation:

1.An increase in temperature increases the energy of the molecules making them move around faster. The faster molecules have a greater chance of colliding and causing a reaction. Remember enzymes are basically catalysts that enable reactions to occur at lower temperatures and energy levels. Enzymes will be destroyed and rendered ineffective if the temperature is too high.

1. Enzymes are very sensitive to pH. There is an optimal pH level for different enzymes, some higher some lower. Extreme levels of pH are harmful to enzymes. If the pH is too low ( too acidic) the enzymes can be destroyed by the acid. If the pH is too high ( too basic) the enzymes will not be able to work.

3,4 increasing the concentration of either or both the substrate that the enzymes reacts with or the enzyme will increase the rate of the reaction. The more molecules of the substrate and the enzymes the more likely the molecules will collide at the right angles for the substrate to be held by the structure of the enzyme allowing the reaction to occur.
