Arrange the following steps of enzyme action in the correct sequential order as described in the catalytic cycle: P. Formation of a new enzyme-product complex (EP) with altered chemical bonds. Q. Release of products from the active site and regeneration of free enzyme. R. Substrate binding to the active site, fitting into the crevice or pocket. S. Induced fit: Enzyme alters its shape to fit more tightly around the substrate. T. Transformation of substrate structure into a transition state structure while bound to the active site.
