  1. 3.4 Diffusion and Osmosis KEY CONCEPTLos materiales atraviesan las membranas debido a diferencias de concentración. La difusión y la ósmosis son dos tipos de transporte pasivo.

  2. 3.4 Diffusion and Osmosis El transporte pasivo consiste en el movimiento de moléculas a través de la membrana sin aportación energética de la célula. También podría describirse como la difusión de moléculas a través de la membrana. • Hay 2 tipes de transporte pasivo. • difusion • osmosis

  3. 3.4 Diffusion and Osmosis Diffusion and osmosis are types of passive transport. • Molecules diffuse down a concentration gradient.

  4. 3.4 Diffusion and Osmosis Diffusion and osmosis are types of passive transport. • Osmosis is the diffusion of water molecules across a semipermeable membrane.

  5. 3.4 Diffusion and Osmosis Diffusion and osmosis are types of passive transport. • There are three types of solutions. • isotonic • hypertonic • hypotonic

  6. 3.4 Diffusion and Osmosis Some molecules can only diffuse through transport proteins. • Some molecules cannot easily diffuse across the cell membrane. • Facilitated diffusion is diffusion through transport proteins.
