A biologist wants to increase the rate of his chemical reaction but has a limited amount of enzyme. He continues to increases th
boyakko [2]

Answer:

The substrate concentration reached Vmax

Explanation:

In this scenerio, further increase in the rate of reaction was prevented because the substrate concentration hit Vmax.

Beyond the Vmax, the substrate can no longer proceed.

  • The substrate is the reactant on which the enzyme works on.
  • Enzymes are natural organic chemical  catalysts.
  • Increasing the concentration of reactants is one of the known and proven ways to speed up the rate of reaction.
  • Since we have limited amount of enzymes, once they all bound to the substrate, no further increase in the substrate will have an effect on the rate.
  • At the optimum reaction point, all the available substrate will bond with the enzyme.
  • Beyond this, the enzymes are saturated will not further any reaction.

Masja [62]

Answers is  F=7.84 N

Friction force resists the effect of horizontal force and trying to approch to a limiting force.

we have formula for limiting friction force between block and floor

               F=Ц N

where N=mg

putting values we get answer.
