Cell Membranes and Transport | IAL Biology | Cambridge 9700 · Edexcel YBI11 · OxfordAQA 9610

Cell membranes and transport for International A Level Biology (AS): the fluid mosaic model, cholesterol, glycoproteins and cell signalling, simple and facilitated diffusion, osmosis and water potential, active transport, endocytosis and exocytosis, the effects of water potential on animal and plant cells, and surface area to volume ratio. 📝 Cambridge 9700 notes: Cell membranes and transport (free): https://www.thinka.ai/en-GB/Cambridge... 📱 Thinka app: practice questions, flashcards and notes: https://www.thinka.ai/en-GB/download?...
