Transport in Plants II: Part A Cells

Transport in Plants II: Part A Cells active transport Contrast · Active transport moves materials from lower to a higher concentration, while passive transport moves materials from higher to lower active transport A key example of an active transporter is the sodium-potassium pump This exports three sodium ions in return for two potassium ions This is key

active transport 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

mc plus active Active transport is the net movement of particles against a concentration gradient Passive transport Osmosis Active transport Facilitated diffusion Cell transport Bulk transport Phagocytosis Vesicular transport Endocytosis
