Question

what is active transport ....??​

Answer 1

Transportation that needs energy is called as active transport.

Answer 2

Answer:

Active Transport is the term used to describe the processes of moving materials through the cell membrane that requires the use of energy.

There are three main types of Active Transport: The Sodium-Potassium pump, Exocytosis, and Endocytosis.

Explanation:

Three sodium ions form inside the cell bind to the pump.

The Phosphate group form a molecule of ATP binds to the pump.

The pump changes shape and the sodium ions are released outside the cell.

Two potassium ions bind to the pump.

The phosphate group is released form the pump and the pump again changes shape and releases the ions into the inside of the cell.
