Examples of active transport include the Sodium-Potassium Pump (primary transport), the Na+/glucose symporter (secondary transport), and endocytosis and exocytosis (bulk transport). An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell. It can occur because the cell contains an ion pump that actively transports ions from one side of . In addition, primary and secondary active transport proteins can also be subcategorized by the number and direction of the molecules being transported. There are several types of bulk transport that are divided into two main categories: exocytosis, which is the transport of large molecules out of the cell, and endocytosis, or the transport of large molecules into the cell. The individual plant cells may have more water than the soil does, but they still need that water. Active Transport The uptake of glucose in the intestine of the human body and also the uptake of minerals or ions into the root hair cells of the plants are some of the examples of active transport.
