Which statement is false about allosteric regulation?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. It is usually the mode of regulation for the last step in reaction pathways since this step produces the final product.

  2. Cellular response is faster with allosteric control than by controlling enzyme concentration in the cell.

  3. The regulation usually is important to the conservation of energy and materials in cells.

  4. Allosteric modulators bind non-covalently at sites other than the active site and induce conformational changes in the enzyme.
