Effect of Enzyme Concentration

Effect of Enzyme Concentration -

Enzyme concentration affects the rate of a reaction.

If the substrate concentration is increased the rate of enzyme reaction also rises.

Beyond a certain point, however, the enzyme becomes saturated with substrate molecules.

Further increase in reaction velocity occurs only if the enzyme concentration is increased.

For example, during starvation the supply of the substrate glucose decreases and glycolysis is depressed.

Conversely increase in glucose concentration accelerates the rate of reaction up to the point when enzyme is saturated with glucose.
