active transport  Active transport บางครั้งเซลล์ต้องการลําเลียงสารจากที่มีความเข้มข้นตํ่าไป ยังที่มีความเข้มข้นสูงกว่ากระบวนการนี้เรียกว่าactive transport  Examples of Active Transport in Plants · Ions moving from soil into plant roots · Transportation of chloride and nitrate from the cytosol to the

The energy for active transport comes from the energy-carrying molecule called ATP Active transport may also require proteins called Active transport uses energy stored in ATP to fuel the transport Active transport of small molecular-size material uses integral proteins in the cell membrane

PRIMARY ACTIVE TRANSPORT Primary active transport occurs in the absence of or against the existing electrochemical gradient, and is powered by metabolic energy Active transport usually happens across the cell membrane There are thousands of proteins embedded in the cell's lipid bilayer Those proteins do much of the
