U2) Bulk Transport + Dilution Series 0.0 / 5 ? BiologyEcology and biodiversityA2/A-levelAQA Created by: lieselb12Created on: 05-05-20 12:15 What does Endocytosis transport + where? Lipids and/or proteins INTO a cell 1 of 8 What is the process? - parts 1+2 Molecules to be transported bind to receptors on cell membrane - causes membrane to change shape + form a vesicle. 2 of 8 What is the process? - parts 3+4 Molecules are then transported into the cell inside the vesicle + the plasma membrane reseals. 3 of 8 What does Exocytosis transport + where? Lipids and/or proteins OUT of a cell 4 of 8 What is the process? - parts 1+2 Vesicles from the golgi containing the molecules to be transported move toward the celll membrane with the energy released from ATP hydrolysis. 5 of 8 What is the process? - parts 3+4 Vesicle fuses with plasma membrane and contents of vesicle are released out of the cell 6 of 8 What is the Dilution Series? A practical technique in which a concentration is used to produce a range of different concentrations 7 of 8 How to work out how much water to add to change a concentration? (desired concentration/ given concentration) x desired volume = cm3 of water needed to be added 8 of 8
