Transport across cell membranes

Down

• 2. The ileum absorbs this monosaccharide through co-transport (7)
• 3. The net movement of molecules/ions from a region of high concentration to a region of low concentration (9)
• 4. Consist of a phosphate ion and two fatty acids chains, meaning that have a hydrophilic 'head' and a hydrophobic 'tail' (12)
• 5. The passage of water from a region of high water potential to a region of low water potential across a selectively permeable membrane (7)
• 6. The transport if one substance coupled with another across a plasma membrane in the same direction, using the same protein carrier (2, 9)
• 7. The movement of molecules/ions into or out of a cell from a region of low concentration to a region of high concentration through the use of ATP and carrier proteins (6, 9)
• 8. The movement of molecules/ions through transmembrane channels and carriers along a concentration gradient (11, 9)
