act on

Respond to information

To act on something is to take action based on it—a tip, an impulse, advice, information: Police acted on an anonymous tip.

The phrase implies moving from knowledge to deed.

Act on also means to affect or influence: The drug acts on the central nervous system.

In legal contexts, a committee or board acts on a proposal by voting or ruling.
