Question
Constants I Periodic Table bu PartB In general, an enzyme has one active site at which catalysis can occur. When the substrates are bound to Refer again to the graph. (Figure 1) In which region is the enzyme saturated with substrate? es the active site, the enzyme will catalyze the reaction. As the concentration of substrate increases, the reaction rate increases, until the point where the active site is saturated with substrate. When the enzyme is saturated, the rate of the reaction will not increase with the concentration of substrates O region A O region B O region C urse Submit Request Answer Figure 1 of 1 Part C Reaction rate vs. substrate concentration Consider a situation in which the enzyme is operating at optimum temperature and pH, and has been saturated with substrate. What is your best option for increasing the rate of the reaction O Increase the pH O Increase the temperature. O Increase the enzyme concentration O Increase the substrate concentrationExplanation / Answer
Part B.
In region C, the reaction rate is the same though the concentration of the substrate has increased. That means, the enzyme is saturated with the substrate in region C.
Therefore, the correct option is the third option (region C).
Part C.
The reaction is happening in optimum termperature and pH. So, changing the temperature and pH will not increase the rate of the reaction.
The enzyme is saturated with substrate. So, there is excess of substrate for which enzyme has to catalyse the reaction. That means, more enzyme is needed to catalyse the reaction. Therefore, increasing the enzyme concentration will increase the rate of the reaction.
The right option is the third option (increase concentration of enzyme).
