Rate of reaction

• What is the definition of the rate of a reaction?

  The rate of a reaction is how fast it is going in a certain time
• What two factors affect the rate of a reaction that is under enzyme control?

  The concentration of substrate and the concentration of enzyme
• What happens when all the active sites have been filled by substrate and the substrate is a limiting reactant?

  The rate of reaction slows down
• What happens when all the active sites and substrate have joined together?

  The reaction produces product
• What happens to the rate of reaction when the substrate concentration is increased at the start of the reaction?

  The rate of reaction increases as there are plenty of active sites to be filled
• How does the rate of reaction change as the reaction progresses and the substrate becomes a limiting reactant?

  The rate of reaction slows down as all the active sites become filled
