Think of it as an engine cylinder that still must do all the work of the compression stroke but doesn’t receive a power stroke in return.

Jake brakes are generally only on some cylinders (stages are driver selectable) for varying amounts of engine braking.
BTW Jake or Jacobs Engine Brake is a brand name for an engine brake.
