Master Transport Across Membranes fast ⚡ – clear explanations, supportive visuals, OCR-aligned.
You’ll cover
• The difference between passive and active transport processes.
• Simple diffusion, facilitated diffusion and osmosis across membranes.
• Active transport and co-transport, including the role of ATP and carrier proteins.
• Bulk transport via endocytosis and exocytosis.
• What net movement and equilibrium mean in the context of transport.
• Factors affecting the rate of transport, including temperature, pH, distance, surface area, molecule size and concentration gradient.
What’s included
• Clear, labelled diagrams showing diffusion, facilitated diffusion and active transport across membranes.
• Visual diagrams of channel proteins, carrier proteins and co-transport systems.
• Structured comparison tables summarising all transport mechanisms, ATP use and suitable molecules.
• Graphs showing the effects of temperature, pH, distance, surface area, molecule size and concentration gradient on transport rate.
• Tables linking exchange surfaces to adaptations that minimise diffusion distance.
• Clear diagrams of endocytosis and exocytosis using vesicles.
• Concise spec reminders embedded alongside diagrams, graphs and tables to reinforce key OCR wording and expectations.
