What happens when substrate concentration is low?

What happens when substrate concentration is low?

(A) At low concentration of substrate, there is a steep increase in the rate of reaction with increasing substrate concentration. The rate of formation of product now depends on the activity of the enzyme itself, and adding more substrate will not affect the rate of the reaction to any significant effect.

What is the relationship between substrate concentration and reaction rate?

The reaction rate still increases with increasing substrate concentration, but levels off at a much lower rate. By increasing the enzyme concentration, the maximum reaction rate greatly increases. Conclusions: The rate of a chemical reaction increases as the substrate concentration increases.

Why does the rate of reaction increase with substrate concentration?

Increasing Substrate Concentration increases the rate of reaction. This is because more substrate molecules will be colliding with enzyme molecules, so more product will be formed.

Do enzymes work better in hot or cold?

Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . Enzymes therefore work best at a particular temperature.

What happens when enzymes get too hot?

Increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. If the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.
