what will be the effect of increasing the substrate concentration in the presence of competitive inhibition? please use a drawing as well if you can. thank you
Homework Answers
Competitive inhibitor binds with the active site of enzyme and decreases the amount of binding the substrate with the enzyme.
So increase substrate concentration can negate the competitive inhibitor and vmax is ultimately affected .
So to overcome competitive inhibitor the substrate concentration should be increased.

Compare competitive and noncompetitive inhibition Question An enzyme is placed in the presence of an unknown substance to determine whether the substance is an inhibitor. As the substrate concentration is increased, the rate of reaction is compared to the normal rate of reaction. Initially, the rate is equal to normal, and as the substrate concentration is increased more and more, the rate of reaction remains the same as the normal rate. What can be concluded about the unknown substance? Select...

A study was conducted to see if increasing the substrate concentration has an appreciable effect on the rate of a chemical reaction. With a substrate concentration of 1.5 mol/L, the reaction was run 16 times with an average rate of 7.5 μmol/L/hr and a standard deviation of 1.5. With a substrate concentration of 2.0 mol/L, 12 runs were made, yielding an average rate of 8.8 μmol/L/hr with a standard deviation of 1.2. a.) Is there any reason to believe that...

2. We can measure how fast the Product is formed at increasing levels of Substrate Concentration The rate of the reaction can be plotted below. This is called a Michaelis-Menten Graph and it shows several important features of the enzyme: a. What happens to the reaction rate as the amount of substrate is increased? reaction rate- b. Why does the graph level off at high levels of substrate concentration? substrate concentration
