question

In the presence of alcohol dehydrogenase, the rate of reduction of acetaldehyde to ethanol increases as the concentration of acetaldehyde is increased. Eventually, the rate of the reaction reaches a maximum, after which point further increases in the concentration of acetaldehyde have no effect. Which of the following is true at the maximal rate of reaction?

category

biology

options

  1. The enzyme's catalytic activity has been reduced.
  2. The change in free energy of the reaction decreases.
  3. The concentration of acetaldehyde has surpassed the enzyme's affinity for it.
  4. The enzyme starts interacting with other molecules instead of acetaldehyde.
  5. The enzyme is no longer specific for acetaldehyde.
  6. The enzyme has been denatured.
  7. Nearly all of the enzyme molecules are interacting with acetaldehyde molecules.
  8. The enzyme molecules are completely saturated with ethanol.
  9. The activation energy of the reaction decreases.
  10. The reaction has reached a state of equilibrium.
