Activation of enzymes and other dynamic molecules: Most enzymes shuttle between conformational states that are catalytically active versus inactive, on versus off. Many hormones affect their target cells by inducing such transitions, usually causing an activation of one of more enzymes. Because enzymes are catalytic and often serve to activate additional enzymes, a seemingly small change induced by hormone-receptor binding can lead to widespread consequences within the cell.
