Mithocondria
It depends. Are you talking about Na/K pumps or Na/K co transporters? Pumps are active.
There are two forms of active bulk transporters. The two forms are exocytosis and endocytosis.
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
Active transport - since pyruvate is ionic is must use protein transporters, and ATP is required
Bulk transporter
The 2 transporters of cellular energy are passive and active transport.
Transporters are the process of active and chemical energy. This is in the body.

Fatty Acid uptake is a done by passive fstty acid transporters and is concentration dependent.

ATP is often used as the source of energy during active transport.
Energy for primary active transport comes from ATP molecules. ATP is produced by the mitochondria. e.g. Na+/K+ ATPases are archetypal primary active transporters and they transport 3 Na+ ions out of cells and 2 K+ ions into cells by hydrolyzing one molecule of ATP. Energy for secondary active transport is stored in an established concentration gradient of ions across the cell membrane and drives transport with the tendency of ions to move from an area of high concentration to an area of lower concentration. e.g. Na+/glucose secondary transporters use the Na+ gradient (higher outside cells than inside) established by Na+/K+ ATPases to transport a molecule of glucose along with a sodium ion into cells.
